How does hydrogen bonding contribute to water's high specific heat?

Hydrogen contributes to water's by allowing water molecules to "stick" to each other.

give water molecules a strong attraction to each other. In order to evaporate water and to energize each water molecule so they can go into a gaseous state, you have to break the hydrogen bonds between each other the water molecules. Since a lot of heat and energy is needed to break hydrogen bonds, water has a relatively high specific heat.

Other liquids, such as liquid nitrogen, have lower specific heats because they are not polar molecules and do not have hydrogen bonds, so in order to evaporate them, you only need to energize the molecules in the liquid to a certain point.
