Q. According to the third law of thermodynamics which one of the following quantities for a perfectly crystalline solid is zero at absolute zero?

Thermodynamics

Solution:

Entropy states the randomness or disorderness of the system. At absolute zero, the movement of molecules of the system or randomenss of the system is zero, hence entropy is also zero.
