Answer
Firstly, it’s important to note that water is both a polar molecule and a molecule that contains hydrogen atoms as part of its structure. With that in mind, we can know that hydrogen bonds do exist between water molecules. We also know that water has a particularly high specific heat (look at table 17.1). From that, one can tell that water has a high heat of vaporization due to the high specific heat as well as the hydrogen bonds. Both the high specific heat and the presence of hydrogen bonds indicate that it will take more energy rather than less to let a molecule of water break from the layers of attractions at the liquid’s surface, which is represented by the large heat of vaporization value.
