Question

Which statement correctly describes one way that the properties of water affect heat and temperature? Water retains more heat than other materials, making coastal ecosystems warmer year-round. Water absorbs heat when it freezes, helping to insulate lakes and ponds from cold temperatures. Water absorbs heat when it changes to vapor, helping to keep animals cool through perspiration. Water retains less heat than other materials, keeping aquatic ecosystems cooler than those on land.

Answer 1

I believe the correct statement is that Water absorbs heat when it changes to vapor, helping to keep animals cool through perspiration. Water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to gas at constant temperature. In humans and other organisms, the evaporation of sweat, which is 90% water, cools the body to maintain a steady temperature.

Answer 2

Answer: Water retains more heat than other materials, making coastal ecosystems warmer year-round.

Explanation:

The water retains more heat than any other material because it has high specific heat. The specific heat can be define as the amount of heat required to raise the temperature of the substance of 1 gram to 1 degree Celsius. The water has high specific heat which indicates that it takes more heat energy to increase the temperature of water as compared to other substance.

It takes several hours to lower down the temperature of the water. The retain heat in water keeps the coastal ecosystem warm year round which favors the survival of the marine animals even in winters.
