    Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. The specific heat of silver is 0.233 J/g-C It is expressed as follows:

    Heat = mC (T2-T1)

    Heat = 250 (0.233) (68.5 - 22.0)

    Heat = 2708.625 J energy absorbed
