WebEnthalpy. The enthalpy of fusion (the symbol is ΔHfus), also known variously as the latent heat of fusion, the enthalpy change of fusion, or the specific melting heat, is the amount of thermal energy which must be absorbed or evolved for 1mol of a substance to change state from a solid to a liquid or vice versa. WebFeb 21, 2024 · 1. Equation (v) is describing the relative heat flows from two different processes, one at constant pressure (where the heat flow at constant pressure, q_p, is given by Delta_H), and one at constant volume (where the heat flow at constant volume, q_V, is given by Delta_E). So it's OK (and, indeed, necessary) to have two different constraints ...
WebFeb 15, 2024 · In symbols, the enthalpy, H, equals the sum of the internal energy, E, and the product of the pressure, P, and volume, V, of the system: H = E + PV.
