Question

Which of these are advantages of high specific heat capacity of water?
A) To enhance blood circulation of a body part to faster healing like doing warm water gargles when injuries are there like ulcers cuts or wounds in mouth.
B) Water remains hot while taking a bath for a longer time than the floor of the bathroom.
C) Water in the sea /river/ ponds remain in the liquid form through cold surrounding climate does allowing habitats to under stay comfortably
D) All of these.

Answer 1

Hint: High specific heat capacity of water means it takes much time or energy to get hot or cold of one unit mass of water. It can also say that due to high specific heat capacity its temperature does not change simultaneously. So, high specific heat capacity of water gives benefits of heated or cooled water for a long time by restraining its temperature.

Complete step by step solution:
Yes, if we drink little hot water in our daily life then we enhance blood circulation of a body part to faster healing of wounds. Like if we gargle in hot water then injuries like ulcers, cuts, and wounds in the mouth.
In winter, or in ordinary days if anyone is taking baths with hot water for a long time then due to water's high heat capacity it doesn’t cool quickly and water remains hot.
Water in aquatic systems remains liquid or not so cool in winters too is due to high specific heat capacity of water. If it doesn’t happen then aquatic life or creatures which depend on water in the sea/ river/ and ponds don't survive.
So, All the given points are advantages of high specific heat capacity of water.

Hence, Option (D) is correct.

Additional Information:
Specific heat is defined by the amount of heat needed to raise the temperature of $1gram$ of a substance $1$ degree Celsius \[\left( {}^\circ C \right)\]. Water has a high specific heat capacity which we'll refer to as simply "heat capacity", meaning it takes more energy to increase the temperature of water compared to other substances. This is why water is valuable to industries and in your car's radiator as a coolant. The high heat capacity of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.

Heat required to change a temperature is given by formula
$\Rightarrow Q=mc\Delta T$ where $Q$ heat is required to change temperature, $\Delta T$ is change in temperature, $m$ is mass of body, and $c$ is specific heat capacity of a body.

Note: We have to remember that there is a difference between specific heat capacity or heat capacity of a body. Specific heat is defined for unit mass of that body while heat capacity is for a constant mass body.
