Third law of thermodynamics

Third law of thermodynamics :- There are several statements for third law of thermodynamics:

1) Nernst statement : The heat capacity of a solid tends to zero, as the absolute zero of temperature approached and the internal energies and entropy of all the substances becomes equal there, approaching common value asymptotically.

2) Planck's statement :  The entropy of every actual substance in the pure state is zero at the absolute zero temperature.

3) Fowler and Gauggenheim's statement : It is impossible by any procedure, to reduce a system to absolute zero temperature in a finite number of operation.
