WebMar 1, 2024 · Two are chosen and tabulated called the principal specific heat capacities. They are the specific heat capacity at constant pressure and the specific heat capacity at constant volume. The first law links the change in internal energy of a system $\Delta U$ to the heat input to the system $\delta Q$ and the work done by the system $\delta W$.
