    To cool the car engineers in radiators, water is   used because it is having

    A)                  high value of specific heat

    B)                  high density

    C)                  low surface tension      

    D)                  low density

    Correct Answer: A

    Solution :

                    The heat absorbed by a substance is directly proportional to its specific heat. Therefore, a coolant having high specific heat will absorb a large amount of heat from the engine. So, water is used as coolant to cool the car engines in radiators.
