Third law of thermodynamics
From Wikipedia, the free encyclopedia
The Third law of thermodynamics says:
- If an object reaches the absolute zero of temperature (0 K = -273,15C = −459.67 °F), its atoms will stop moving.
The statement is: At absolute zero, the entropy of a perfectly crystalline substance is zero.
Experimentally,it is not possible to obtain -273.15°C.It is found that most of the gases either liquified or solidified before reaching such a lower temperature and gases molecules(always exist as polyatomic molecule-Avagadro's law)does not remain.
