According to third law of thermodynamics, the entropy at 0 K is zero for

(a) elements in their stable form
(b) perfectly crystalline solids
(c) substances at 1 atm and $25^\circ C$
(d) $N_2O$

1 Answer

Answer: perfectly crystalline solids
For perfectly crystalline solids at 0 K, all molecular motion ceases and particles are closely packed. Thus, randomness and hence entropy is minimum.
