What is the highest temperature in the Universe?
It's amazing, but the most heat in the Universe of 10 trillion degrees Celsius was obtained artificially on Earth. According to the resource, the absolute temperature record was set on November 7, 2010 in Switzerland during an experiment at the Large Hadron Collider - LHC (the world's most powerful particle accelerator).
As part of an experiment at the LHC, scientists set the task of obtaining quark-gluon plasma, which filled the Universe in the first moments of its origin after big bang. To this end, at a speed close to the speed of light, scientists collided beams of lead ions with colossal energy. When heavy ions collided, “mini-big explosions” began to appear - dense fiery spheres that had such a monstrous temperature. At such temperatures and energies, the nuclei of atoms literally melt and form a “broth” of their constituent quarks and gluons. As a result, quark-gluon plasma with the highest temperature since the origin of the Universe was obtained in laboratory conditions.
Before this, in no experiment had scientists ever been able to obtain such an unimaginably high temperature. For comparison: the decay temperature of protons and neutrons is 2 trillion degrees Celsius, the temperature neutron star, which is formed immediately after a supernova explosion, is 100 billion degrees.
Our native Sun is a yellow dwarf and has a core temperature of 50 million degrees. Thus, the temperature of the resulting quark-gluon plasma was 200 thousand times higher than the temperature of the solar core. At the same time, pristine cold usually reigns in the surrounding space, since average temperature The universe is only 0.7 degrees above absolute zero.
What is the coldest temperature in the Universe?
Now guess where and how the lowest temperature in the Universe was obtained? Right! Also on Earth.
In 2000, a group of Finnish scientists (from the laboratory low temperatures University of Technology in Helsinki), which studied magnetism and superconductivity in rare metal“Rhodium”, it was possible to obtain a temperature of 0.1 nK - writes. This is currently the lowest temperature recorded on Earth and the lowest temperature in the Universe.
The second lowest temperature record was set at the Massachusetts Institute of Technology. In 2003, they managed to obtain ultra-cold Sodium gas.
Obtaining ultra-low temperatures artificially is an outstanding achievement of mankind. Research in this area is extremely important for studying the effect of superconductivity, the use of which (in turn) can cause a real industrial revolution.
In nature, the lowest temperatures were recorded in the Boomerang Nebula. This nebula expands and ejects cooled gas at a speed of 500,000 km/h. Due to enormous speed release of gas molecules cooled to -271 °C. This is the lowest officially recorded natural temperature.
For comparison. Typically, in outer space the temperature does not drop below -273 °C. The lowest temperature in the Solar System, -235 ° C on the surface of Triton (a moon of Neptune). And the lowest natural temperature on Earth, -89.2 °C, is in Antarctica.
IN summer months Over the past few years, we have increasingly complained about the unbearable heat of July or August. This topic always comes up in everyday conversations, where we complain about unbearable climatic conditions. It is especially difficult for residents major cities. The same topic regularly appears on the pages and in videos of the media: “Today the highest temperature in the last n years was recorded...” and “The temperature record was broken again...” In this regard, it would be interesting to know what temperatures are generally possible in our planet.
And above all about Russia
Yes, it was in our country that one of the weather temperature records was recorded. Only it was not the maximum, but the lowest. In the city of Oymyakon, which is located in Yakutia just 350 kilometers south of the Arctic Circle, a temperature of -71.2 °C was recorded. This happened in 1926. For a resident middle zone or southern regions, it’s even difficult to imagine such cold! By the way, city residents immortalized this moment by establishing
Vostok station
And this record again belongs to the Russians. The station may not be located on the territory of the country (it is located in Antarctica), but it is the fruit of the labors of Soviet science and engineering. And it was here in 1983 that air quality across the entire planet was recorded. This figure was -89 °C.
Canadian frosts
The country is the northernmost in the Western Hemisphere, so it's no surprise that Canada also boasts (or complains about) record low temperatures. On "Eureka" average annual temperature is -20 °C. And in winter it regularly drops to -40 °C.
Sultry Libya
Now let's walk a little through places whose temperatures sharply contrast with those above. After all, here is the highest temperature on the planet! For example, Libya is famous for its incredibly high temperatures. And in the town of Al-Aziziya, which is 40 kilometers south of Tripoli, the highest temperature on Earth was recorded among settlements. In September 1922 it was +58 °C. A real inferno, in comparison with which the heat of our country will seem like a light spring warmth!
And again Libya
If native Russia presented us with the lowest temperature records, then otherwise it is Libya that is in the lead. In 2004-2005, the local Dashti Lut desert recorded the highest temperature in earth's surface. It was +70 °C. Interestingly, this same desert is also the driest place on Earth (along with the Chilean desert. Not a single thing is able to survive here. Living being, even bacteria!
Hot Ethiopia
But in this country the average annual highest temperature throughout to the globe. The local area of Dallol is located 116 meters below sea level and is covered with volcanic salt. Of course, nothing living lives here. And the temperature in these conditions is +34.4 °C on average per year.
Temperature may vary. And high degrees occur not only in some place on Earth, but also in specific person or in a specific device.
Experts say that the highest average annual temperature, which was recorded for six years (from 1960 to 1966), was registered in Ethiopian Dallol. Then thermometers showed plus 34.4 degrees Celsius. The volcanic crater Dallol, however, is famous for the fact that it is practically all year round the air temperature remains at the same level, approximately plus 34 degrees. The crater is located 48 meters below the sea level, its diameter reaches almost one and a half meters. This place has another name - “the gates of hell.” It is quite difficult to stay here for a long time. However, there are indigenous people here. Local people Tribes are distinguished by their taciturnity and aggressiveness.
But in the American Death Valley, for 43 days in a row (this is from July 6 to August 17, 1917), the air warmed up to plus 48.9 degrees Celsius.
Death Valley
In Western Australia, namely in Marble Bar, the average temperature was higher than plus 32.2 degrees Celsius. And this lasted exactly 162 days in a row from October 30, 1923 until April 8, 1924. At the same time, the maximum temperature was plus 48.9 degrees Celsius.
The highest temperature on Earth, plus 58 degrees (and this is in the shade!) was recorded in the Libyan place of Al-Aziziya. It is located at an altitude of 11 meters at sea level. The record was recorded on September 13, 1922. On the same day in Saudi Arabia thermometers showed plus 58.4 degrees. The difference in readings is not so significant; it can be compared with the measurement error. Therefore, two places are considered the hottest in the world, that is, they have the highest temperatures.
Lunch without fire
Already in the new century, records continued. In the Libyan desert of Dashti Lut in 2005, experts noted that thermometers showed plus 70 degrees Celsius. To date, this is the highest temperature that has been recorded in the natural environment.
In such weather, a person can safely cook food without using fire. At plus 70, objects heat up under the sun so much that, for example, a car hood turns into a heated frying pan. And you can easily cook yourself first-class scrambled eggs with it. However, in such heat it is impossible to walk barefoot on the ground. In the shade the air warms up to plus 60 degrees.
And even despite such sultry weather, streams of tourists constantly flock to the Dashti-Lut desert. This place, in addition to its record temperatures, is famous for its high dunes. They can reach half a kilometer in height.
Hot stars
It turns out that the stars also glow with heat. The temperature of the substance in their depths is measured in millions of Kelvin. And the energy of almost all the luminaries is released after thermonuclear reactions converting hydrogen into helium. The process takes place in internal areas at high temperatures. In the depths of stars, temperatures can reach 10-12 million degrees Kelvin.
Artificial temperature
Well, the highest temperature that man could create is about 10 trillion degrees Kelvin. For comparison, such heat was supposed to exist during the creation of the Universe. A record degree was obtained in 2010 at the Large Hadron Collider during the collision of lead ions, which were accelerated to near-light speeds.
However, this is not the only record artificial temperature in the world. American physicists It has been possible to reach enormous temperatures in laboratory conditions since the creation of the Universe. This was done by colliding gold ions at Brookhaven National Laboratory. During the experiment, gold ions collided in a collider. Scientists have obtained a quark-gluon plasma (after the Big Bang, the Universe consisted of a similar quark-gluon plasma for a few microseconds) with a temperature of approximately 4 trillion degrees Celsius. She only lasted a few milliseconds. But this time was enough to obtain data for research for several years.
For comparison, the temperature of the Sun's core is 50 million degrees, and that of a neutron star that formed after a type 2 supernova explosion is about 100 billion degrees Celsius. It turns out that the resulting substance has a temperature tens of thousands of times higher.
These studies, scientists say, make it possible to understand the processes that took place at the early stage of space development. And as a result, physicists plan to get closer to understanding why matter emerged from a homogeneous primordial mass.
Theoretically, the highest temperature is the Planck temperature. Temperatures above this simply cannot exist, since everything will be converted into energy. The record Planck temperature is approximately 1.41679(11)×1032 K (this is approximately 142 nonillion Kelvin).
The Large Hadron Collider
Previously, the highest temperature in the world was considered to be 520 million degrees Celsius. This is 30 times higher than the temperature at the center of the Sun. This figure was obtained on May 27, 1994 at the Princeton Plasma Physics Laboratory in the Tokamak experimental reactor.
Man and cat...
The highest temperature that has been recorded in a person is 46.5 degrees Celsius. Theoretically, such heat leads to fatal outcome. However, a 52-year-old man with such a thermometer reading was cured. This was done by doctors at the American Grady Memorial Hospital, in the state of Georgia. The record was recorded in the summer of 1980 and was included in the Guinness Book of Records. After a 24-day course of treatment, the man was discharged from the hospital. Theoretically, a temperature of 42ºС - 43ºС is lethal for humans, since it is at this temperature that proteins coagulate and metabolism in brain tissue is disrupted.
In animals normal temperature body exceeds the usual human 36.6 degrees. And among the record holders for thermometer readings is chicken. Her body temperature can rise to 42 degrees. Much higher temperature lizard body. In the sun it is 50-60 degrees. And this despite the fact that experts classify lizards as cold-blooded. Well, the most warm-blooded are birds. For their body, the norm is 42 degrees. The need for high temperature is explained quite simply - flight requires birds to have a high metabolic efficiency.

What's the weather like? In principle, it is possible to live at +50°C and -50°C, and even in a greater range. Air conditioners, fans and jackets will help us with this. Well, someone, of course, will die and nothing can be done about it, because we don’t live in a terrarium.
What is the lowest air temperature ever recorded on Earth?
The lowest air temperature on Earth was recorded at the Soviet Antarctic Vostok station on July 21, 1983, when the platinum thermometer at the weather site showed -89.2°C. This is the lowest temperature ever recorded meteorological observations.
The lowest temperature recorded in our country is -78°C. Incredible frost occurred in the upper reaches of the Indigirka River.
The lowest air temperature in inhabited areas of the planet was recorded in 1964 in Yakutia in the village of Oymyakon - -71.1°C. The entire interfluve of the upper reaches of the Yana and Indigirka rivers is considered to be the region of the cold pole of the Northern Hemisphere.
What is the highest air temperature ever recorded on Earth?
The highest temperature on Earth recorded in Libya in 1922 is +57.8°C.
The highest soil temperature was recorded at Shurchi station in Uzbekistan. The temperature of irrigated light gray soils here reaches 79°C. At the Repetek station in Turkmenistan, the sand is heated to 77°C.
Which maximum temperature Can a person withstand outside air?
A person may be exposed to dry air at very high temperatures for a short time. A person can tolerate temperatures of 160°C. This was proven by English physicists Blagden and Chantry, who conducted an experiment on themselves. A person can tolerate a temperature of 104°C for 26 minutes, 93°C for 33 minutes, 82°C for 49 minutes, and 71°C for 1 hour; This was established during experiments with healthy human volunteers.
What is the minimum outdoor temperature that a person can withstand?
It depends on the state of his health and clothing, but most importantly - on the speed of the wind. In Yakutia in winter, people spend hours in the cold, with air temperatures below -50°C, but they are dressed appropriately, and in the conditions of the central part of the Siberian anticyclone there is usually no wind. In Antarctica, winterers from continental stations also have to spend quite a long time outdoors, but there very coldy often accompanied strong wind. Therefore, warm, windproof clothing is not enough there, and people are forced to wear a mask or cover their faces with the hood of a fur jacket (“parkas”). The staff of research stations in the Arctic and Antarctic, who by the nature of their work are forced to regularly be outdoors, sometimes use electrically heated clothing, which weighs less than ordinary warm clothing, is less bulky, and less restricts movement. Minimum temperature, at which people spent a short time in the air, is -88°C.
And two more facts
Maximum temperature hard objects, with which people can contact for a long time - about 50 degrees Celsius (at a higher temperature a burn occurs).
At a constant body temperature of more than 42°C, a person dies.
The science
Temperature is one of the fundamental concepts in physics; it plays a huge role in concerns earthly life of all forms. At very high or very low temperatures, things can behave very strangely. We invite you to learn about a number of interesting facts related to temperatures.
What is the highest temperature?
The highest temperature ever created by man was 4 billion degrees Celsius. It's hard to believe that the temperature of a substance can reach such incredible levels! This temperature 250 times higher temperature of the Sun's core.
An incredible record was set in Brookhaven Natural Laboratory in New York at the ion collider RHIC, the length of which is about 4 kilometers.
Scientists forced gold ions to collide in an attempt to reproduce conditions of the Big Bang, creating quark-gluon plasma. In this state, the particles that make up the nuclei of atoms—protons and neutrons—break apart, resulting in a “soup” of constituent quarks.
Extreme Temperatures in the Solar System
The temperature of the environment in the solar system is different from what we are used to on Earth. Our star, the Sun, is incredibly hot. At its center the temperature is about 15 million Kelvin, and the surface of the Sun has a temperature of only about 5700 Kelvin.
Temperature at the core of our planet is approximately the same as the surface temperature of the Sun. The most hot planet solar system– Jupiter, whose core temperature 5 times higher than the surface temperature of the Sun.
The most cold temperature in our system is recorded on the Moon: in some craters in the shadow the temperature is only 30 Kelvin above absolute zero. This temperature is lower than the temperature of Pluto!
Temperature of the human environment
Some peoples live in very extreme conditions And unusual places, not entirely convenient for life. For example, some of the coldest settlements are the village of Oymyakon and the city of Verkhnoyansk in Yakutia, Russia. The average winter temperature here is minus 45 degrees Celsius.
The coldest is more Big City is also located in Siberia - Yakutsk with a population of about 270 thousand people. The temperature there in winter is also about minus 45 degrees, but in summer it can rise up to 30 degrees!
The highest average annual temperature was seen in an abandoned city Dallol, Ethiopia. In the 1960s, the average temperature was recorded here - 34 degrees Celsius above zero. Among large cities, the city is considered the hottest Bangkok, the capital of Thailand, where the average temperature is in March-May also about 34 degrees.
The most extreme temperatures where people work are seen in gold mines Mponeng V South Africa. The temperature at about 3 kilometers underground is plus 65 degrees Celsius. Measures are taken to cool the mines, such as using ice or insulating wall coverings, so miners can work without overheating.
What is the coldest temperature?
Trying to get lowest temperature, scientists were faced with a number of important things for science. Man has managed to obtain the coldest things in the Universe, which are much colder than any thing created by nature and the cosmos.
Freezing allows the temperature to drop to several milliKelvins. The lowest temperature that has been achieved under artificial conditions is 100 picoKelvin or 0.0000000001 K. To achieve this temperature, it is necessary to use magnetic cooling. Also, such low temperatures can be achieved using lasers.
At these temperatures, the material behaves completely differently than under normal conditions.
What is the temperature in space?
If, for example, you take a thermometer into outer space and leave it there for a while in a place far from a source of radiation, you may notice that it shows the temperature 2.73 Kelvin or so minus 270 degrees Celsius. This is the lowest natural temperature in the Universe.
Temperature stays the same in space above absolute zero due to the radiation that remained after the Big Bang. Although space is very cold by our standards, it is interesting to note that one of the most important problems that astronauts face in space is heat.
The bare metal from which objects in orbit are made can heat up to 260 degrees Celsius due to free sun rays. To lower the temperature of ships, they need to be wrapped in a special material that can only lower the temperature by 2 times.
Temperature outer space nevertheless constantly falling. Theories about this have been around for a long time, but only recent measurements have confirmed that the Universe is cooling by about by 1 degree every 3 billion years.
The temperature of space will approach absolute zero, but will never reach it. Temperature on Earth does not depend on the temperature that exists in space today, and we know that our planet Lately gradually warms up.
What is caloric?
Warm – mechanical property material. The hotter an object, the more energy its particles have while moving. Atoms of substances in a hot solid state they vibrate faster than atoms of the same but cooled substances.
Will the substance remain in liquid or gaseous state depends on to what temperature should it be heated?. Today, any schoolchild knows about this, but until the 19th century, scientists believed that heat itself was a substance - weightless fluid, named caloric.
Scientists believed that this fluid evaporated from the warm material, thereby cooling it. It can flow from hot objects to cold ones. Many predictions based on this theory are actually correct. Despite misconceptions about heat, many have actually been made correct conclusions And scientific discoveries . The caloric theory was finally defeated at the end of the 19th century.
Is there a highest temperature?
Absolute zero- a temperature below which it is impossible to fall. What is the highest possible temperature? Science cannot yet answer this question accurately.
The highest temperature is called Planck temperature. This is exactly the temperature that existed in the Universe at the moment of the Big Bang, according to ideas modern science. This temperature is 10^32 Kelvin.
For comparison: if you can imagine, this temperature billions of times higher than the highest temperature, obtained artificially by man, which was mentioned earlier.
According to the standard model, the Planck temperature remains the highest possible temperature. If there is something even hotter, then the laws of physics we are used to will stop working.
There are suggestions that the temperature may rise even higher than this level, but science cannot explain what will happen in this case. In our model of reality, anything hotter cannot exist. Maybe reality will become different?
