Latent comes from the Latin latere which means to lie hidden or concealed.

. The heat of fusion for water at 0 C is approximately 334 joules 797 calories per gram and the heat of vaporization at 100 C is about 2230 joules 533 calories per gram. The energy needed to completely vaporize a mole of a liquid. The latent heat of vaporization is what.

Does heat of vaporization change with temperature. In the process of heat conduction thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. It neither goes up nor down.

Latent heat of vaporization Latent heat of vaporization is the heat consumed or discharged when matter disintegrates changing stage from fluid to gas stage at a consistent temperature. HEAT OF VAPORIZATION used as a noun is very rare. When a material in liquid state is given energy it changes its phase from liquid to vapor.
