According to the third law of thermodynamics which one of the following quantities for a perfectly crystalline solid is zero at absolute zero? (a)Free energy (b)Entropy (c)Enthalpy (d)Internal energy

Assertion : Third law of thermodynamics is confined to pure crystalline solids. Reason : Theoretical arguments and practical evidences have shown that entropy of solutions and super cooled liquids is not zero at 0 K.

Write third law of thermodynamics.
