Third law of thermodynamics

From Simple English Wikipedia, the free encyclopedia

The third law of thermodynamics says:

The definition is: at absolute zero , the entropy of a perfectly crystalline substance is zero.

Experimentally, it is not possible to obtain −273.15°C, as of now. It is found that most of the gases either liquify or solidify before reaching such a temperature, gaseous molecules no longer remaining. So far, scientists have been able to get close to, but not exactly, absolute zero. This may change in the future.
