WebSep 8, 2024 · Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water … In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). It is equal to the cohesive energy of the solid. For elemental metals, it is also equal to the standard enthalpy of formation of the gaseous metal atoms. The heat of sublimation is usually expressed in kJ/mol, although the less … WebRelation of enthalpy of sublimation with enthalpy of fusion and enthalpy of vaporisation: The enthalpy of sublimation of ice at 0 0 C and 1 atm pressure is 51.08 kJ mol −1.H 2 O(s) → H 2 −1 at 0 0 C.
