Question

Mention the applications of high specific heat capacity of water.

Answer 1

To provide the appropriate solution of the given question, we need to first dig into the concept of specific Heat capacity which is basically the amount of heat required to change the heat content of exactly $1gram$ of a material by exactly ${{1}^{\circ }}C$. It is formulated by the expression $Q=Cm\vartriangle T$
Where $Q$ is the quantity of heat absorbed;
$m$ is the mass of the body;
$\vartriangle T$ is Rise in temperature;
$C$ is the specific heat capacity of a substance that depends on the nature of the material of the substance. The $S.I.$unit of Specific heat capacity is $Jk{{g}^{-1}}{{K}^{-1}}$ .

Complete answer:
Water is having the highest specific capacity and therefore, takes comparatively longer time to heat and cool down and Following are few applications of high specific heat capacity of water:
Hot water bottles are used for fomentation, as the water remains hot in the bottle for a long time in spite of dissipating off large quantities of heat.
Water is used as coolant car radiators for its high specific heat capacity, due to which it can absorb a large amount of heat energy from the engine of the car, without its temperature rising too high.
In many countries with low temperatures, wine bottles are kept under water for it takes a long time for the temperature to fall to ${{0.0}^{\circ }}C$ due to its high specific heat capacity.

Note:
One is advised to remember that the exact specific heat capacity of liquid in its liquid state or specific heat capacity of liquid water is one calorie which is equal to $4.184Joules$ and specific heat capacity for water vapor for room temperature is even higher than most of the materials.
