These cookies track visitors across websites and collect information to provide customized ads. For example, the specific heat of water is 1 calorie (or 4,186 joules) per gram per Celsius degree. These hydrogen bonds are some of the strongest of all intermolecular forces, so a large amount of energy is needed to break these interactions this is the main reason why water has such a high relative boiling point. Why does water have a high specific heat Water covers around 70% of the Earths surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature. Answer (1 of 36): Water's high heat capacity is a property caused by hydrogen bonding among water molecules. The enthalpy of vaporization (symbol Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. Climate change, and global warming specifically, are adding lots of heat to the atmosphere. At a certain point, the molecules will begin to break away from the liquid and vaporize.
