At 0K, the entropy of pure crystalline materials is zero. ∴ The statement (I) is correct as entropy approach zero, at absolute zero. statement (II) entropy for the process, H2O(l)→H2O(g) decreases is incorrect as entropy increases. The degree of randomness when water vaporises to gaseous statē increases. (III) Gibbs' energy is a state function is correct as the Gibbs' free energy depends on initial and final state only. Hence, statement (I) and (III) are correct.
