How does the molar entropy of a substance change with increasing temperature

The molar entropy of a substance increases with the increasing temperature.  

Explanation:

With the increase in temperature, the randomness of the system enhances as more amount of energy is imparted into the system, which results in the excitation of molecules. Entropy is directly equivalent to the disorderness or randomness of the system. Thus, the molar entropy of a substance elevates with the rise in temperature.
