Answer:Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
Explanation:Water actually has one of the highest specific heat capacities of all the substances on Earth. Hydrogen gas, helium gas, and aqueous (liquid) ammonia are a few substances with a higher heat capacity than water.
