Expert Answer
Water is used in hot water bottles and coolants as well because specific heat of every liquid varies with the temperature. But water shows a very peculiar behavior that is at
, its specific heat is 
, its specific heat is 
, its specific heat is 
Since the specific heat of water is large, therefore, by absorbing or releasing large amounts of heat, temperature of water varies or changes by small amounts. Hence it is used in hot water bottles and also as coolant in radiators.
