What is absolute 0 degrees, and what is absolute 0 degrees?

Theoretically there is a minimum temperature at which the particles stop all thermal motion, and this temperature becomes absolute zero. Experimentally, it can't be reached, only infinitely close. Unit Kelvin, which is used to measure the temperature of Celsius 0 Kelvin = Celsius, or 0 degrees Celsius = Kelvin.

Celsius, absolute low temperature, the state in which all particles stop moving.

minus 273 degrees Celsius is absolute zero infinitely close to the lowest temperature in the universe.

Absolute 0 degrees is minus.

Absolute zero is the lowest thermodynamic temperature, but this is the theoretical lower limit. The unit of the thermodynamic temperature scale is Kelvin (k), and absolute zero is the zero point defined by the Kelvin temperature scale. 0K is approximately minus degrees Celsius.

The temperature of a substance depends on the kinetic energy of the atoms, molecules, etc. within it.

According to Boltzmann, the higher the kinetic energy of the particle, the higher the temperature of the substance. Theoretically, if the kinetic energy of the particle is as low as the lowest point of quantum mechanics, the matter reaches absolute zero and cannot be lower. However, absolute zero can never be reached, it can only be approached infinitely.

Because any space must contain energy and heat, and they are constantly converting into each other without disappearing.

The origin of absolute zero:

Kelvin is a unit of thermodynamic temperature named after the surname of the British scientist Kelvin. In 1848, the British scientist Duanlian Thomson first proposed the theory of "thermodynamic temperature", which was soon recognized internationally. In 1854, William Thomson proposed that the unit of thermodynamic temperature could be determined by selecting a fixed point.

As early as 1787, the French physicist Charles discovered that when the pressure is constant, the increase in the volume of a certain amount of gas (expansion rate) is a fixed value for every 1 increase in temperature, and the volume expansion is linearly related to the temperature. Reputation.

The initial experiments gave the value of 1 269 to the volume of the gas at 0, which was later revised by a number of people after decades of experiments, notably the work of the Frenchman Guy Lussac in 1802. The above gas volume vs. temperature is expressed by the formula as follows: v v0 (1 t.

Absolute zero is the lowest temperature in thermodynamics, but only a theoretical lower limit.

The unit of the thermodynamic temperature scale is Kelvin (k), and absolute zero is the zero point defined by the Kelvin temperature scale (referred to as the Kelvin temperature scale, denoted as k). 0k is approximately equal to minus degrees Celsius on the temperature scale, which is 0 degrees Kelvin, at this temperature, the molecules of the object have no kinetic energy and potential energy, and the kinetic potential energy is 0, so the internal energy of the object is 0 at this time.

The temperature of a substance depends on the kinetic energy of the atoms, molecules, etc. within it. According to the Maxwell-Boltzmann distribution, the greater the kinetic energy of the particle, the higher the temperature of the matter.
