Using the equation:
Assuming C is constant:
Using the third law of thermodynamics:
ΔS = ∫[0.1T/T]dT (from 5 to 10 K) = ∫0.1dT (from 5 to 10 K)
Without the exact function for C(T), we cannot calculate the exact value of S(0). third law of thermodynamics problems and solutions pdf
S(0) = S(20) - ∫[C/T]dT (from 0 to 20 K)
Using the third law of thermodynamics, we can write: Using the equation: Assuming C is constant: Using
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?
