Question

What is Enthalpy of Sublimation?

Answer

The enthalpy of sublimation is the amount of energy required to transform a solid directly into a gas, bypassing the liquid phase. It is defined as the heat absorbed per unit mass of substance during sublimation at constant temperature and pressure. The enthalpy of sublimation can be calculated using the following equation: Δ_subH = Δ_fusH + Δ_vapH
