set by whom? Why is the highest temperature in the universe at 140,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, and the lowest temperature at -273.15 degrees Celsius?
Appropriate temperature is a necessary condition for the survival and reproduction of life. A living body is like a complex machine. The internal processes of operation are complex and diverse, and some require suitable temperature conditions. The earth is one of the eight planets in the solar system, orbiting the sun, and the average distance from the sun is 150 million kilometers, this distance is defined as "astronomical unit". The fusion of hydrogen nucleus has been going on in the core of the sun. Every second, 600 million tons of hydrogen undergo fusion reaction to generate 595 million tons of helium. During the whole process, there will be 5 million tons of mass loss. The equation translates into energy, which eventually travels outward in the form of light and heat. On different orbits of the solar system, the solar radiation energy received is naturally different. For example, Mercury and Venus are like purgatory on earth, while Pluto, which is far away, was the ninth largest planet. It is a completely frozen world. The earth is in an appropriate position, and the received solar radiation energy is just right, which makes the earth have a suitable temperature, which can meet the survival and development needs of life. The location of the earth is the habitable zone of the solar system. After leaving the earth, humans will be greeted by extreme cold or scorching high temperature. The lowest temperature is -273.15°C as the limit, while the highest temperature can reach 140,000,000,000,000,000,000,000,000.
Temperature does not equal heat
In our regular consciousness, temperature and heat are the same, and we listen to the weather forecast every day to decide whether to add clothes the next day To keep warm, or to reduce the cooling of clothes, in simple terms, we use hot and cold to define temperature, or just rely on temperature to determine hot and cold. To give a simple example, we know that the temperature of the surface of the sun can reach 5,500 degrees Celsius, and the temperature of its corona can reach 1 million degrees Celsius. The highest melting point substance currently possessed by humans is tetratantalum hafnium pentacarbonide, whose chemical formula is Ta4HfC5, and its melting point can be to 4215 degrees Celsius. But the human Parker Solar Probe can operate in the corona at a temperature of 1 million degrees Celsius without melting. In fact, the difference between temperature and heat is completely explained here. Temperature actually only shows the intensity of thermal motion of microscopic particles, and heat is the energy actually received by an object. Steaming in a sauna with a high temperature of 60 degrees Celsius and bathing in water with a temperature of 60 degrees Celsius must give people a completely different feeling.Who determines the highest and lowest temperatures in the universe?
There is a limit to the temperature in the universe. The lowest temperature is -273.15°C, which is called absolute zero, and the highest is 140,000,000,000,000,000,000,000,000,000,000,000,000,000,000 million. Set, why can't it be other numbers? 01. The highest temperature of the universe is the intensity of the thermal motion of microscopic particles, which can be referred to as the speed of particle motion. The current mainstream view holds that the universe was born in the Big Bang 13.82 billion years ago, and at the moment of the Big Bang is the particle heat. The moment when the movement is the most intense, and the temperature will continue to decrease after the Big Bang. Therefore, it is said that the temperature at the beginning of the universe was up to 140,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. From another point of view, there is the limit of the speed of light, and the intensity of thermal motion of microscopic particles also has the highest limit. 02. The lowest temperature in the universe The lowest temperature in the universe is called absolute zero, which is the lowest temperature in thermodynamics. Absolute zero is absolute zero (0K, -273.15°C, -459.67°F), which is different from the highest temperature. The theoretical minimum value is completely unattainable in real life. The lowest temperature found in the universe so far is in the Boomerang Nebula, 3,000 light-years away from us, a cloud of gas around a dying star, where the temperature drops rapidly as the heat is drawn away, where the temperature is about It is minus 272 degrees Celsius or about 1 Kelvin. At the lowest temperature in the laboratory, scientists cooled ytterbium atoms to just one billionth of a degree Celsius above absolute zero, the latest research has been published in the journal Nature Physics. The so-called absolute zero is to stop the movement of all microscopic particles, but this situation is not allowed to exist. From the perspective of quantum mechanics, the uncertainty principle is actually very simple to explain the uncertainty of microscopic particles. If the kinetic energy of the microscopic particles is zero and stops moving, then the uncertainty principle is "determined", so it is impossible for this situation to happen.It is said that at the end
the highest temperature Planck temperature and the lowest temperature absolute zero are the results supported by the current scientific system, and also have a theoretical basis, and from the present In some cases, no cases of breaking the temperature limit have been found. As for who sets it up? It can only be said that the universe is such a law of development!
