That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Waterâs heat of vaporization is around 540 cal/g at 100 Â°C, water's boiling point. Note that some molecules of water â ones that happen to have high kinetic energy â will escape from the surface of the water even at lower temperatures.
One gram of water takes 4.184 joules of energy to increase its temperature 1 ÂºC. This is the most energy any substance takes to raise its temperature 1 ÂºC. In contrast to taking the most energy to raise its temperature 1 ÂºC, this means that it also takes the longest to cool down. This means that water has the highest heat capacity. It must release 4.184 joules of energy in order to decrease its temperature by just 1 ÂºC. The heat water releases is absorbed by its environment. Knowing the heat capacity of water, it is possible to find how well its environment insulates it.
