Why does the entropy of a substance increase with an increase in temperature?
(N/A) As the temperature increases,the kinetic energy of the molecules increases,leading to an increase in their translational,rotational,and vibrational motions. This results in greater disorder in the system,which corresponds to an increase in entropy.
