I am currently continuing at SunAgri as an R&D engineer. Necessary cookies are absolutely essential for the website to function properly. Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature. A high heat capacity means that more energy is required to increase the temperature of water by 1 degree so it requires more time to heat or cool. The vaporization is the opposite process of condensation. Because the high pressure steam gave up its latent heat in going through the phase change from liquid to gas (water to steam). Why does water have such high heat of evaporation? Why does dichloromethane have a low boiling point? The latent heat of vaporization is higher than the latent heat of fusion since gas molecules have the largest intermolecular space and the force of attraction between the molecules is almost negligible. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. Likewise, the high latent heat of vaporization (see below), indicates that when water vapor (derived from evaporation of water at the oceans surface driven by solar energy receipt at low latitudes) condenses into liquid droplets at high elevations or high latitude, the latent heat is released into the environment.
