where S(T) is the entropy at temperature T, S(0) is the entropy at absolute zero, C is the heat capacity, and T is the temperature.

Without the exact function for C(T), we cannot calculate the exact value of S(0). third law of thermodynamics problems and solutions pdf

Problem 1: Entropy Change near Absolute Zero A certain system has an entropy of 10 J/K at 10 K. If the temperature is decreased to 5 K, what is the change in entropy? where S(T) is the entropy at temperature T,

ΔS = 0 as T → 0 K

Assuming C is constant:

Since we are not given C, we cannot calculate the exact value of ΔS. However, we can say that ΔS approaches 0 as T approaches 0 K. The heat capacity of a system is given by C = 0.1T J/K. Calculate the entropy change between 10 K and 5 K. If the temperature is decreased to 5 K,
