Detailed explanation-1: -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.

Detailed explanation-2: -The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances. As the temperature rises, the hydrogen bonds between water continually break and reform, allowing for the overall temperature to remain stable, although increased energy is added to the system.

Detailed explanation-3: -Water has a higher specific heat capacity because of the strength of the hydrogen bonds. It requires a significant of energy to separate these bonds.

Detailed explanation-4: -For water vapour at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 1.9 J/g°C. As with most liquids, the temperature of water increases as it absorbs heat and decreases as it releases heat.
