How much heat is required to vaporize 18.5g of water at 100c ? The heat of vaporization of water at 100c is 40.7kj/mole .
To eliminate heating the bodies of water surrounding the power plant, the evaporation of the coolant water is what cools the steam; the water vapor generated by this evaporation is released to the atmosphere
