Hydrogen bonds contribute to water’s high specific heat (amount of heat needed to raise the temperature of 1 gm of a substance 1oC) - due to the fact that hydrogen bonds must be broken to increase the kinetic energy (motion of molecules) and temperature of a substance --> temperature fluctuation is minimal.

Water has a high heat of vaporization - large amount of heat is needed to evaporate water because hydrogen bonds must be broken to change water from liquid to gaseous state.
