Energy to evaporate water equation
WebQ.1: If the heat of vaporization for water is 2257 joule per gram. Then, calculate the amount of heat energy that we need to apply to vaporize 145 grams of water. Use Heat of Vaporization Formula. Solution: Given … WebEvaporation. Evaporation is the process in which a liquid changes to the gaseous state as the free surface, below its boiling point, through the transfer of energy. Evaporation is a cooling process- the latent heat of vapourisation (~585 cal/g of evaporated water) must be provided by the water body. Rate of evaporation depends on.
