Question

water has a unique property on cooling and heating.explain​

Answer 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. ... In fact, the specific heat capacity of water is about five times more than that of sand. This explains why the land cools faster than the sea.

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Answer 2

When heat is absorbed , hydrogen bonds are broken and water molecules can move freely.......Water molecules are polar , so they from hydrogen bonds. This gives water unique properties , such as a relatively high boiling point, high specific heat , cohesion and density.
