Detailed explanation-1: -The correct answer is-Water efficiently absorbs and retains heat. Explanation: High specific heat is water’s capacity to gradually warm-up and cool down. This permits water to help keep up homeostasis in the human body.
Detailed explanation-2: -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.
Detailed explanation-3: -Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.
Detailed explanation-4: -Specific heat is the amount of heat needed to raise the temperature one degree Celsius. High specific heat is waters ability to slowly heat up and cool down. This allows water to help maintain homeostasis in the human body. The heat stored in water is moving to the surface, evaporating while taking heat with it.
Detailed explanation-5: -Furthermore, water has a high specific heat because it takes a lot of energy to raise or lower the temperature of the water. As a result, water plays a very important role in temperature regulation. Since cells are made up of water, this property helps to maintain homeostasis.
