Why the temperature can t go below absolute zero?

Temperature is a measure of the thermal motion of a system, but the solution of the Schrödinger equation tells us that the system still has thermal motion even below zero. The third law of thermodynamics says that when the temperature approaches zero, the entropy change caused by the possible changes in the system approaches zero. One of its equivalent descriptions is that absolute zero is unattainable.

There's something called negative temperature, but it's not a very low temperature, it's a positive temperature, which is a special system case.

Because the matter in the vacuum has a certain amount of energy, and when these substances are removed, the object reaches absolute zero when the density of the universe is at its lowest. Because there is no absolute vacuum, it does not exceed the minimum density of the universe.

That's because under the current technology, there is no ability to continue to lower the temperature, of course, it is even more impossible in nature, so with absolute zero, it may not be possible in the future.

Reach absolute zero to stop the molecules of the object in motion.

If the temperature is reduced to absolute 0 degrees.

Then the whole universe would not exist。When the temperature drops to absolute 0 degrees, the kinetic energy of the molecules of the object is zero, and at the same time the internal energy reaches a minimum of a relative threshold, which means that there will be no vibrations by any particles in this space, so the volume of this space is zero. In short, no object, including time and space, exists, and therefore the universe does not exist.

As the most important temperature scale and thermodynamics in the scientific community.

And the most important parameter of statistical physics, absolute 0 degrees also belongs to the concept of thermophysics. This concept was developed in 1848 by a generation of Kelvin.

Founded by Baron William Toms. The modern view of space-time holds that time, space, and matter complement each other and coexist with the universe.

No one can exist independently, because space is the container of matter, matter is the content of space, and without matter, there is no space, and it can be said that there is no need for space to carry silver, and without space, there is no place for matter, and there will be no matter. Therefore, if the temperature drops below absolute 0 degrees, it means that there is no time, space and matter, and of course there is no universe and no us.

Quantum mechanics argues that classical theories of time and space will no longer be applicable in extremely small spaces and in very short periods of time, and that a new scale will need to be established to measure these times and spaces. Although no more plausible explanation has been found, superstring theory.

But it is the most promising. To put it bluntly, there is a huge absolute zero energy in a completely vacuum, free of particles, matter, and space.

It is also based on the universe of the great **.

The causes and roots of the formation.

When humans create temperatures, they realize Einstein.

Condensed matter, also known as the bose of matter. This is a completely new form of matter – the boson.

Atoms, such as the common photon and rubidium-87 and atoms, are reduced in temperature close to absolute zero.

It is a special state of matter, with superconductivity and gas properties.

Although humans have created a low temperature close to absolute 0 degrees, it is not a large space, but a small space that cannot be captured by the naked eye. Even scientists.

The space between the balls and the nursery made in the magnetic wells of a high vacuum is so small that it is not even as small as a hair or a needle tip. Extremely sophisticated instruments are required to be explored and photographed for human reference.

All in all, although many scientific research teams have created a temperature that is critical to absolute 0 degrees, it is only approximate. Absolute 0 degrees does not occur in our world. Because once the temperature drops below absolute 0 degrees, all the particles will no longer move, and there will be no space and time.

has lost its malleability.

And the persistent particles will no longer be able to form the four-dimensional blind hidden space in which we live.

All things will be reduced to nothingness.

Absolute zero is one of the lowest temperatures that modern scientists have studied. When the temperature drops to absolute 0 degrees Celsius in the manuscript, all the creatures on the Hidden Potato Rock of the Stove Noble Society cease to exist.

At this time, the specific heat capacity of the substance in any process tends to be close to 0.

Because of absolute zero.

, all the motion of atoms and particles will be frozen; And the high temperature does not. We all know that there has always been an "extreme low temperature" in the universe. In physics, it is named "absolute zero".

Normally, it is minus 273 degrees; This represents the lower limit of temperature; However, the universe has extreme low temperatures, but it seems that there are no extreme high temperatures. Is 273 degrees above zero the limit? No kidding, the surface of the sun is 8,000 degrees Celsius.

Finish; The temperature of the Earth's inner core is above 30,000 degrees Celsius.

There is the highest temperature in the universe.

Since motion determines temperature, if the velocity of the molecule is infinitely fast and the kinetic energy is infinite, can't the temperature be infinite? Since it is a substance, it must obey the basic laws of matter, and the speed of matter has a limit. Special Theory of Relativity.

It is described that the propagation of information and energy cannot exceed the speed of light, and that matter with a non-zero mass at rest cannot reach the speed of light, but can only approach infinitely, so there is an upper limit to temperature.

In addition, everything in the universe originates from the original eruption of scorching energy, so the highest temperature is the temperature that compresses the entire universe back to that extremely dense and almost blowout. Electromagnetic waves emitted by an object.

The shorter the wavelength, the greater the energy and the higher the radiation temperature. In the theory of black-body radiation, the physicist Planck.

It was discovered that energy is not continuous, but one by one. The smallest unit of each copy that cannot be divided again.

Call it quantum.

Absolute zero. At absolute zero, the particles are actually still moving. According to the laws of thermodynamics, absolute zero is unattainable, so we can't measure absolute zero, we can only get it theoretically. And in quantum mechanics.

There is a cornerstone theory called the uncertainty principle.

Some people translate this theory as the uncertainty principle.

This is the physicist Heisenberg.

Proposed, he found that there is no way to measure the two parameters of the particle, momentum and position, at the same time. If the momentum is measured, the position is not accurate; If the position is accurate, the momentum cannot be measured.

To put it bluntly, there is no way to know the velocity and position of a particle at the same time, which is determined by the properties of the particle itself. If the particle is stationary, then we can know its position and velocity at the same time, which is contrary to the theory of quantum mechanics. So, in fact, at absolute zero, the particles are still vibrating in a small area, rather than being completely still.

Epilogue. Speaking of which, I am reminded of a cutting-edge technology called "laser cooling". In general, lasers can only be used for heating because electromagnetic waves transfer energy to the object, causing an increase in the internal energy of the object.

However, since there is a direct relationship between temperature and atomic vibration, the laser can also exert a reverse force on the atoms, moving the atoms to the molecules.

The amplitude of the vibration is greatly reduced, thus achieving the purpose of cooling it. The current low temperature limit is mostly achieved in this way, and it is already very close to absolute zero.

Because the heat can keep rising, absolute zero is indeed only 0 degrees.

Because it has been studied in thermodynamics in physics, cold and heat are not the essence of temperature, in fact, they are actually the irregular vibrations of molecules and atoms inside the object; Therefore, when the vibration is stopped, a certain low temperature is reached, but there is no certain limit to the stop of high temperature.

It's right"Temperature"The concept looks at the understanding. In fact, temperature is a physical quantity used to describe the speed of the thermal motion of molecules inside an object. According to the theory of molecular motion, all objects are composed of molecules (here the molecule is different from the chemical molecule, it also includes atoms, clusters of atoms, etc.), and the molecule is doing a never-ending thermal motion.

That is, the molecules of any object are constantly moving, which is used to indicate how fast or slow they are moving"Temperature"It can't be zero. In fact, thermodynamic zero is only a theoretical temperature, and the temperature of any object can only be infinitely close to it and cannot reach it. There is no fast upper bound on temperature because the average velocity of molecules can be infinite.

On this question, I think, why can the minimum temperature only reach minus 273 15 degrees Celsius, in fact, because the minimum temperature minus 273 15 degrees Celsius is already the limit, then you may ask, why minus 273 15 degrees Celsius is the limit, in fact, the temperature in the world is caused by particles, and because the higher the temperature, then the more active his particles are, and after the temperature reaches minus 273 15 degrees Celsius, the particles have stopped moving, so even cooling is useless, Because minus 273 15 degrees Celsius is absolutely zero.

As we all know, we don't know the maximum temperature of heat, for example, in our opinion, the sun is about 50 degrees, but the sun is far away from the earth, everyone knows that the speed of light is the fastest, there is also an opinion that if time exceeds the speed of light, it will go retrograde, and now the maximum temperature that humans refer to is 15 million degrees, and this temperature is uncertain, even this temperature can be higher, this is the temperature of the solar coronal layer calculated by humans.

It is not only the temperature of the sun that we are familiar with, but also lightning, 28,000 degrees is just the average temperature of lightning, the speed and temperature of lightning are very rare on earth, and the reason why lightning is famous is that lightning strikes every year, and on earth, on average, there are people who are unlucky, they are struck by lightning every year, although some people are still alive, but lightning has a great impact on the human body.

It has been argued that under the current theory, the highest temperature is the Planck temperature. Any object with temperature radiates electromagnetic waves. It is easy to understand that each of us emits electromagnetic waves outward, and the wavelength of electromagnetic waves is related to temperature, the higher the temperature, the shorter the wavelength, according to classical quantum mechanics, the shortest wavelength is Planck length.

The corresponding temperature is Planck temperature with a value of 1 41x10 32 K.

As for the question of why there is no upper limit to the pure land temperature of the high brigade, there is an absolute zero limit to the low temperature, which is explained here today.
