    The coldest absolute zero should be more than minus 270 degrees, but there is no absolute high temperature in the universe, just like the temperature on the surface of the sun, nuclear fusion fission reactions occur every day, so there is no maximum upper limit for temperature.

    Absolute zero is the temperature of an atom in a stationary state, it has no kinetic energy. And the magnitude of kinetic energy determines the temperature level, so there is no absolute high temperature because there is no maximum value of kinetic energy.

    Because there are so many things in the universe that are unpredictable, and there are so many things that are unknown. The movement between molecules can generate heat, but how fast the molecules move is unknown.

    There should be no absolute zero, because it is impossible to reach absolute zero. When we study a problem, we only study it from a theoretical point of view.

    In fact, the universe has an absolute high temperature, but it is in the theory of existence, that is, the high temperature at the starting point of the universe. Later, as the universe continued to expand, cooled, and the temperature kept dropping.

    Absolute zero. i.e. 0 Kelvin blind mountain land.

    is according to the thermodynamic temperature scale.

    an ideal temperature scale that does not rely on the physical system). This is the definition in thermodynamics and is the earliest.

    Absolute zero is the most powerful compared to the lowest temperature in the universe.

    But thermodynamics is a "phenomenology" theory, and neither gives a theory of the reasons behind it nor the physical mechanism. So, from here alone, we don't get its physical substance. In fact, not to mention absolute zero, it is the concept of "temperature" on which it depends, and the definition given in thermodynamics is also "operational", similar to volume and pressure, which is the state parameter of the thermodynamic system.

    According to the zero law, when two thermodynamic systems come into contact, if they are in thermal equilibrium from the beginning, i.e., there is no macroscopic heat exchange between the two systems, then we say that the two systems have the same temperature. Therefore, we do not know from here what the physical essence of temperature is.

    Later, like Maxwell.

    They developed classical statistical physics. According to its molecular kinetic theory.

    Temperature is a measure of the average translational kinetic energy of a bunch of molecules. "Translation" means that it does not include "rotation", "internal vibration" or anything like that. According to this logic, absolute zero should be a condition in which the molecules are at rest (if the molecules have no structure and do not rotate), i.e., the translational kinetic energy is zero.

    This is the image given in the classical physical era.

    However, this absolute zero degree is only the theoretical minimum temperature, and there is no such low temperature environment and objects in nature, and some scientists believe that absolute zero is just an illusion, and it is indefatigable in reality. Because any object has its own energy, it is impossible to be completely in a state of zero energy.

    We may not be able to imagine this absolute zero, and in human beings, we usually think that the low temperature is below 0 degrees, when it reaches 0 degrees, the liquid water will freeze, and when it is dozens of degrees below zero, the hardness of the liquid water into ice cubes is very strong, and the gas has its boundary value, when the temperature is lower than this critical value, the gas will also become liquid or even solid. For example, oxygen, methane. Wait.

    Absolute zero refers to the temperature of minus 170 180; Absolute zero, because the temperature that human beings can accept is only guessed to be minus ten degrees Celsius, and absolute zero can reach minus a few or anything will be converted into gas or liquid again, human beings are unable to accept this temperature leakage, which will cause great safety to human life and will also cause some harm to the ecosystem.

    The average temperature of the universe is about 3 degrees above absolute zero, so even the smallest and hottest black holes are much warmer than the average temperature of the universe. As a result, the thermal radiation of black holes is minimal, and they are completely submerged in the cosmic microwave background radiation.

    It is considered absolute zero, neither in nature nor in the laboratory, it is impossible to create such a temperature judgment, which isA theoretical minimum temperature in thermodynamicsYesThe temperature of matter when the kinetic energy of the particle is as low as the lowest point of quantum mechanics, but according to the third law of thermodynamics, this absolute zero can never be reached, it is just a thermodynamic concept.

    The temperature of a substance depends on the average kinetic energy of particles such as atoms, molecules, etc., within it, at absolute zero, constitutes the place of matterThere are molecules and atoms that stop moving, but because there is still potential energy, soIt will only be infinitely close to absolute zero, without being able to reach absolute zero.

    Since there is a lower limit to the temperature, there should also be an upper limit on the contrary, and the high temperature is not endless as many people think. According toThe Great ** Theory of the Modern Universe, the universe originated from oneThe dense and hot singularity is large**We live in this big process, and all the heat and temperature are in this singularity.

    That is to say,The temperature of the singularity itself is the highest temperature in the universeAccording to the cosmic radiation theory, as long as there is temperature, there are radiating electromagnetic waves, and the wavelength is inversely proportional to the temperature.

    With the development of quantum mechanics, the shortest spatial length of the wavelength has also been calculatedPlanck lengthIn this way, the highest temperature in the universe, which is the Planck temperature, can be reversedIt's about x 10 32 k, a huge number.

    Of course, this is also theoretically an absolute high temperature, includingIt is impossible for a star such as the Sun to achieve such a temperature through nuclear fusionDegree. The artificially manufactured high temperature has been able to reach more than 500 million degrees Celsius, and it is still used in the physical shelter and noise laboratoryA plasma mixture of deuterium and tritium undergoes nuclear fusionwhen the high temperature is generated.

    of our countryCirculator No. 2M deviceIn Chengdu, the temperature of the plasma ions in the excavation and limb of the device was reachedBillion degrees Celsius, which is the highest temperature manufactured by scientific researchers in our country.

    So, scientifically theoreticallyThere is the concept of absolute zero, and there is also the concept of maximum temperature, but both are only theoretical temperatures, which are impossible to reach in reality.

    No, because the temperature of the sun is relatively high, the closer you get to the sun, the higher the temperature will be, and there is no highest standard.

    Temperature refers to the physical quantity that represents the heat and coldness of an object, and modern physics indicates the intensity of the microscopic particle motion inside the object, that is, the more intense the particle motion, the higher the temperature. Absolute zero is the lowest temperature in the universe. What is the highest temperature in the universe?

    In terms of thermal power, the unit of temperature is "Kelvin", which is usually denoted by the word k, and absolute zero is defined as zero point. When all the particle motion in the object stops, it reaches 0 Kelvin (k), defined by the thermal force known as "absolute zero", where 0k is the degree Celsius.

    <>So, if the lower limit of temperature is absolute zero, is there an upper limit? What is the highest temperature in the universe? The high temperature at the limit of the universe in which we are located is considered to be the temperature of the large ** initial float time (the smallest unit of time), i.e., this is also known as the float temperature.

    Why, because at the initial moment of the universe, all the energy of the entire universe is concentrated in a "special point", which represents the highest temperature of the entire universe.

    However, the floating temperature cannot theoretically be said to be the upper limit of the temperature, as seen before, if the speed of motion of the particles in the object reaches the limit, the temperature will reach the limit. It is well known that the speed of light is the limit of velocity, but when the speed of motion of the particles inside an object reaches the speed of light, this temperature is the upper limit. The relativistic effect shows that it is impossible for a particle with mass to reach the speed of light, and when its speed is close to the speed of light, the mass increases indefinitely, and the corresponding kinetic energy increases indefinitely.

    Because the intensity of a particle is proportional to its own operating energy, there is no upper limit to the temperature of an object as long as there is a continuous input of energy!

    However, the temperature without an upper limit is a theoretical thing, and in the universe in which we live, the lower limit of temperature is absolute zero, which is impossible, and the fact that it can only be close to infinity must be respected. The upper limit of temperature in the universe is the Planck temperature, which is the highest temperature produced by the universe.
