Answer 1

Answer is D. Water has high specific heat.

1 calorie/gram °C or 4.186 joule/gram °C is the specific heat of water, which is high as compared to any other common substance. The high specific heat of water due hydrogen bonds present between water molecules. In order to increase temperature of water, this bond needs to be broken down. To break many hydrogen bonds, a larger amount of energy is required. when all the bonds are broken water is changed from liquid to gas( water vapor).
