john_es · Answer

You must use the formula,
$$Q=m\cdot c\cdot \Delta T$$

anonymous · Answer

and what does each variable in that represent?

john_es · Answer

Q is the heat energy the answer for, m is the mass in grams, c is the specific heat from the table for the aluminium, and T is the variation of temperature in Kelvins.

Do you understand how to apply?

anonymous · Answer

so 28 X 64.7 X 0.897?

john_es · Answer

Perfect. The result is in Joule, don't forget to specify it in the solution.
