Answer: A. The hydrogen bonds cause water to resist a change in temperature.
Explanation:
Heat of vaporization is defined as the amount of heat required to convert 1 mole of liquid to gaseous state.
Water has high heat of vaporization due to the presence of strong hydrogen bonds between hydrogen and a electronegative element oxygen. As the water molecules are strongly bonded to each other, large amount of heat is required to raise the temperature of water.
The molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.
