In this equation, r … WebMay 13, 2024 · For gases, there are two possible ways to evaluate the change in entropy. We begin by using the first law of thermodynamics: dE = dQ - dW. where E is the internal energy and W is the work done by the system. Substituting for the definition of work for a gas. dQ = dE + p dV. where p is the pressure and V is the volume of the gas. tent ministryWebAll thermodynamic relations can be obtained from statistical physics. However, one cannot consider statistical physics as superior to thermodynamics. The point is that thermodynamic relations are universal because they are model-independent.
