It has high specific heat

Vedclass · Answer

(C) The correct option is $(C)$.Water is used as a coolant in engines primarily because it has a very high specific heat capacity $(c \approx 4186 \ J/kg \cdot K)$.Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by $1 \ ^\circ C$.Due to its high specific heat,water can absorb a large amount of heat energy from the engine with only a relatively small increase in its own temperature.This makes it an extremely efficient medium for transferring heat away from engine components,preventing them from overheating.
