1. Heat (Q) evolved is Q = mc?T where m is the mass in grams, c is the specific heat and ?T is the change in temperature. In this case, the change in temperature is in degreesCelcius and the energy is in calories. You can do conversion in the final answer to joules if you want using;

1cal = 4.18joules.

hope that helps
