WebJan 30, 2024 · The enthalpy change of Step 1 is the molar heat of fusion, \(\Delta H_{fus}\) and the enthalpy change of Step 2 is the molar heat of vaporization, \(\Delta H_{vap}\). Combining these two equations and canceling out anything that appears on both sides of the equation (i.e., liquid water), we're back to the sublimation equation: WebThe equation for enthalpy is h = ha + H*hg where ha is the specific enthalpy of dry air, H is the humidity ratio, and hg is the specific enthalpy of water vapor. You can look online for a steam table and use that to determine hg (the specific enthalpy of water vapor).
