Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
It requires a lot of heat input in order to raise the temperature of water. This is because water has a high
A
surface tension
B
density
C
specific heat
D
RBI
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: -Heat capacity of water It takes a lot of heat to increase the temperature of liquid water because some of the heat must be used to break hydrogen bonds between the molecules.

Detailed explanation-3: -The heat energy required to raise the temperature of of a substance through is called its specific heat capacity.

Detailed explanation-4: -Explanation: The high specific heat of water means that it requires a large amount of heat to raise the temperature of water. This helps the temperature of the environment from becoming too hot or too cold. Also, humans are about 66% water, thus this property of water helps us regulate our body temperature too.

Detailed explanation-5: -specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree.
