Specific latent heat of vaporization si unit

WebAug 23, 2024 · This shows that the latent heat of vaporization goes into two things: To increase the internal energy upon vaporization (especially the increase of potential energy as the molecules are pulled apart from each other) and the PdV work done against the external pressure as the volume increases. 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.
