Evaporation energy change
WebThe constructed evaporator with all-in-one function provides an effective way for commercial, portable photothermal conversion to achieve seawater purification. Conflict of Interest The authors declare no conflict of interest. … The enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. The enthalpy of vaporization is often quoted for the normal boiling temperature of the substance. …
