The Latent Heat of Vaporization of Water The Latent Heat of Vaporization of Water Aim: The aim is to determine the latent heat of vaporization of water by doing an experiment of boiling water. Theory: The latent heat of vaporization is the amount of energy that is required to transfer a kg of liquid from the liquid state to the gaseous state. This transformation appears‚ when water is heated. The temperature of the water keeps increasing‚ until it
