Absolute Temperature (The Third Law of Thermodynamics)

As substances cool, their molecules move with less speed and their kinetic energy decreases. Actually, it can be shown that the kinetic energy of particles is directly proportional to the temperature. To rephrase, temperature can be seen as a measure of the kinetic energy of particles. It is therefore easy to understand that at temperatures of absolute zero, all molecular motions stop, and entropy approaches zero.

The Third Law of Thermodynamics:

There is a temperature so low that it cannot be reached. This temperature is called absolute zero kelvin (-273.15°C)
