Third law of thermodynamics
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, 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.
