Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?
A
Water is an acid.
B
Water is a versatile solvent.
C
Water has a high heat capacity.
D
Water acts as a buffer.
Explanation: 

Detailed explanation-1: -To summarize, large bodies of water tend to moderate the temperature of nearby land due to the high heat capacity of water. This high heat capacity results from both the higher specific heat of water and the mixing of heat throughout a greater depth over oceans.

Detailed explanation-2: -Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats. This means that their temperatures change more quickly.

Detailed explanation-3: -Because of its high heat capacity, water can minimize changes in temperature. For instance, the specific heat capacity of water is about five times greater than that of sand.

Detailed explanation-4: -What property of water explains why large bodies of water do not quickly fluctuate in temperature? Water has a high specific heat capacity, so it takes a lot of energy to increase its temperature.

Detailed explanation-5: -The energy required to break multiple Hydrogen bonds causes water to have a high heat of vaporization. A large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
