Detailed explanation-1: -Answer and Explanation: If water had a low specific heat compared to a high specific heat, life would not have evolved as it has. The hydrogen bonding network in water is what allows water to have such a high specific heat.
Detailed explanation-2: -18.12 Water has a much higher specific heat than most other covalent compounds. What do you predict might happen if water had a low specific heat instead? A. Flooding would occur and animals would be forced to migrate.
Detailed explanation-3: -Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances. This is why water is valuable to industries and in your car’s radiator as a coolant.
Detailed explanation-4: -The high specific heat of water means that we only lose a small amount of heat when the sweat on our skin evaporates. Water plays a major role in our bodies’ chemical reactions. Water plays a much more important role in plants than in animals, due to the role of water in photosynthesis.
Detailed explanation-5: -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.
