heat capacity; temperature ; equal; calorimeter.
Now on the first, the question is poorly worded. Heat given off is equal to the product of mass x specific heat capacity x change in temperature.
Those three things define heat change. In olden days, mass x specific heat content was called heat capacity, it is seldom used that way any more. So Heat change would be heat capacity x change in temperature in those terms.
