Heat gained or lost is mass times specific heat times change in temperature.

the specific heat of aluminum is 0.9 j/g k. the specific heat of copper is 0.39 j/g k. if samples of equal mass of both aluminum and copper are heated up to 100°c and then dropped in a cold water bath. compare the heat lost by the two samples.
a) there is not enough information to conclude anything.
b) the copper loses a little more than twice the heat of the aluminum.
c) the aluminum loses a little more than twice the heat of the copper.
d) the heat lost is the same because the temperature change is the same.
