You use the formula you listed under "Relevant equations"

It is often listed as Q=m x c x ΔT to emphasise the change in temperature. You will also need to look up the specific heat capacity of Aluminium [the c].

NOTE: metal names end in "ium" Calcium, Sodium, Ferrium [Iron] etc. That is why it is actually Aluminium :rolleyes:
