    Given:

    64.82 g of aluminum metal

    100.0oC is cooled to 82.0 °C

    specific heat of aluminum is 0.897 J / g °C.

    Required:

    Change in heat energy

    Solution:

    This can be solved through the equation H = mCpT where H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.

    The specific heat of the water is 4.18 J/g-K

    Plugging in the values into the equation

    H = mCpT

    H = (64.82) (0.897 J / g °C) (82 - 100)

    H = - 1,046.6 J
