Third Law of Thermodynamics

Which of the following allotropes of sulphur has maximum $\mathrm{S}$ at $0° \mathrm{K}$?

Cotyledons are also called-

Among the following, the reaction that is accompanied by a decrease in the entropy is

Entropy is a measure of disorder. For perfect crystalline substances at $0\mathrm{K}$, entropy becomes:

For a perfectly crystalline solid C_p,m = aT³ , where 'a' is constant. If C_p,m is $\text{0.42 }\frac{\text{J}}{\text{K mol}}$ at 10 K, molar entropy at 20 K is :

Which law of thermodynamics help in calculating entropy at different temperatures?

The entropy of a perfectly crystalline material is zero at 0 K. This is statement of
