Web22 mei 2024 · Enthalpy is represented by the symbol H, and the change in enthalpy (delta H) in a process is H2 – H1. There are expressions in terms of more familiar variables such as temperature and pressure: dH = CpdT + V (1-αT)dp. Where Cp is the heat capacity at constant pressure and α is the coefficient of (cubic) thermal expansion.
