    Which one of the following has the highest value of

    specific heat?
    A Glass Correct Answer Incorrect Answer
    B Copper Correct Answer Incorrect Answer
    C Lead Correct Answer Incorrect Answer
    D Water Correct Answer Incorrect Answer

    Solution

    The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation. The specific heat per gram for water is much higher than that for a metal.
