WebΔHsub - enthalpy of sublimation - heat required to change a solid into a gas One Enthalpy of particular use is the Enthalpy of Formation. The Standard enthalpy of formation (ΔH oF) is the heat change that results when one mole of a compound is formed from its elements (in most stable form/natural) at a pressure of 1 atm. WebThe amount of energy needed to sublime 1 mol of a substance is its enthalpy of sublimation (ΔHsub) and is the sum of the enthalpies of fusion and vaporization. Plots of the temperature of a substance versus heat added or versus heating time at a constant rate of heating are called heating curves. robert preston as centauri https://lconite.com
