Third law of ThermodynamicsAdminAug 28, 20201 min readThe entropy of pure substance at a temperature is 0. Since there is no uncertainty about the state of molecules at that time.This statement is called Third Law of thermodynamics.

Entropy change for various processEntropy change for constant pressure process We know that dS = ʃ δQ/T for P = C, Q = mCpdT dS = mCp ʃ dT/T dS = mCp ln (T₂/T₁) (V₁/V₂) = (T
General gas Equation for entropy changeConsider a certain quantity of perfect gas being heated by any thermodynamic process. Let m = mass of gas P₁ = initial pressure of gas V₁ =
