Answer:
Thanks to its high specific heat, water plays a very important role as a temperature regulator
Explanation:
The specific heat is the amount of heat needed per unit mass to raise the temperature one degree Celsius. The specific heat of the water is 1 calorie / gram. Water is one of the substances with higher specific heat and this is why water plays a very important role as a good temperature regulator.
Water changes its temperature, absorbs or loses a large amount of heat but only changes, either by increasing or decreasing its temperature very little. This property is essential for living beings as it reduces drastic changes in temperature. It also helps that our body does not overheat or over cool since this property helps us maintain thermal balance.
