Heat question!??the amount of heat gained or lost by a substance is equal to
 
1. The problem statement, all variables and given/known data

the amount of heat gained or lost by a substance is equal to the product of its______ times the change in__________ times its__________

2. Relevant equations
none that i know of


3. The attempt at a solution
I dont know the first blank or the third, but is the second heat?

The second is not heat. Have you been given any equations in your classes when you've been talking about calorimetry? If not I suggest you look up calorimetry on google. You're bound to find the answer then.

so the answer is energy, mass, and specific heat?

You still need this part: the change in__________
Not "energy." The heat IS energy.
