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.
