WebNov 26, 2024 · Latent Heat of Fusion. In the case of solid to liquid phase change, the change in enthalpy required to change its state is known as the enthalpy of fusion (symbol ∆H fus; unit: J), also known as the (latent) heat of fusion. Latent heat is the amount of heat added to or removed from a substance to produce a phase change. WebThe fusion and solidification of the paraffin wax were modeled via the apparent specific heat capacity method [44], which models the latent heat as a temperature-dependent function presenting peaks at the characteristic temperatures of phase change, to be added to the specific heat capacity. The peaks were described by Gaussian functions, whose ...
