The property of water that shows it takes a lot of energy to raise water 1 degree. This helps stabilize the environment and organisms and cells that are made mostly of water.
A
High Specific Heat
B
Adhesion
C
Cohesion
D
Ice Floating on Top of Water
Explanation: 

Detailed explanation-1: -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-2: -The hydrogen bonds between water molecules cause the water to have a high heat capacity, meaning it takes a lot of added heat to raise its temperature.

Detailed explanation-3: -Heat capacity of water In other words, water has a high specific heat capacity, which is defined as the amount of heat needed to raise the temperature of one gram of a substance by one degree Celsius.

Detailed explanation-4: -Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules.

Detailed explanation-5: -The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.
