Tables show (latent) heat of vaporization of various chemical substances under normal conditions (1013,25 hPa, 25 °C).
Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas. ...
The Heat (or Enthalpy) of Vaporization is the quantity of heat that must be absorbed if a certain quantity of liquid is vaporized at a constant temperature. ... The list of enthalpies of vaporization given in the Table T5 bears this out. Example \(\PageIndex{1}\)
J.A. Dean (ed.), Lange's Handbook of Chemistry (15th Edition), McGraw-Hill, 1999; Section 6, Thermodynamic Properties; Table 6.4, Heats of Fusion, Vaporization, and Sublimation and Specific Heat at Various Temperatures of the Elements and Inorganic Compounds
After this the temperature remains constant until the enthalpy of vaporization (ΔH m) has been supplied. Once all the liquid has been converted to vapor, the temperature again rises. In the case of water the molar enthalpy of vaporization is 40.67 kJ mol –1. In other words \[\ce{ H2O(l) ->[100^{o} \text{C}] H2O(g)} \nonumber \]
