Water has a high specific heat. so, it takes a lot of energy to increase the temperature of water. this makes water very useful in stabilizing the temperature on earth. which of these explain water having a high specific heat? a) water contracts as it melts. b) water has an unusually high boiling point. c) water is polar, so the molecules are held tightly together. d) water is an inorganic molecule, so heat does not affect it as quickly.

Answer;

C) Water is polar, so the molecules are held tightly together.

Explanation;

-Water has a high specific heat, meaning that a relatively large amount of heat must be added or removed in order to get the temperature of the water to change significantly. Water is able to absorb a high amount of heat before increasing in temperature, allowing humans to maintain body temperature.

-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.
