Chapter 6, Water Vapor 6-7 Table 6-1. Latent Heat of Water at 0 °C Latent Heat Type Energy Exchange (J/g) Latent heat of sublimation 2,834 Latent heat of vaporization 2,501 Latent heat of fusion 334 The amount of energy associated with latent heat exchange should not be understated. An average hurricane releases 52 million trillion (5.2 x 1019) joules per day as water vapor condenses into clouds and precipitation. This is equivalent to about 40 times the total worldwide energy consumption per day in 2005!
