What is the third law of thermodynamics?
The third law of thermodynamics states that absolute zero, the lowest possible temperature, can never be reached.

The entropy of a system is zero at absolute zero. A procedure can remove a portion of the entropy, but not all of it. Thus it would take an infinite number of repetitions of the procedure to reach absolute zero. It’s been possible to achieve temperatures as low as a few billionths of a kelvin, but it has never been able to reach absolute zero.
