Equation relating temperature and pressure
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. WebDec 14, 2024 · Find the Density of Gases.
