1.	Third law of thermodynamics is only applicable for perfectly crystalline substances.(a) true(b) falseThe question was posed to me during a job interview.My question comes from Thermodynamics in section Thermodynamics of Chemistry – Class 11
Answer» Right option is (a) true The explanation: We can define the THIRD law of thermodynamics ENTROPY of a perfectly crystalline substance at zero kelvin or absolute zero is taken to be zero, but this is not APPLICABLE if there is any IMPERFECTION at 0 k, the entropy will be larger than 0.
