Addition of heat to a system increases the randomness in the system due to increase in molecular motions. Generally, a system at a higher temperature has greater randomness than at lower temperature. Thus, temperature too helps in the measurement of randomness of particles in a system. Heat added to a system at lower temperature causes greater randomness than in comparison to when heat is added to it at a higher temperature. Thus, entropy change is inversely proportional to the temperature of the system.
Q/T
Decreases.. change in entropy=enthalpy/temp.
