Change in entropy during constant volume process is given as: = m cv ln (T2 / T1) Change in entropy during polytropic process i.e. (PVn = constant) = m cv…

The second law of thermodynamics can also be stated using Clausius, Kelvin and Planck statements also. Each statement is based on an irreversible process. The Clausius and the Kelvin and…
Entropy is a measure of the degree of randomness of the molecules comprising the system. Higher the disorder, greater is the increase in entropy. Entropy is the function of a…
Entropy Principle: Form the Clausius inequality, ∫ δQ / T ≤ 0 As the entropy is a property of the system, therefore the cyclic integral of a property is zero…
The various relationships between internal energy (U), enthalpy (H), Helmholtz free energy (a) and Gibbs free energy (g), with relevant parameters such as entropy, pressure, temperature and volume are given…
In order to prove that entropy is a property, we will suppose two cycles i.e. 1-A-2-B-1 and 1-A-2-C-1 as shown in For a reversible cycle 1-A-2-B-1: ∫1-A-2 δQ / T…
