25 minutes is enough for the pan to get to 232oC. So we have initial (22oC) and final (232oC) temperatures. Aluminium specific heat capacity is 0.215 cal/g/oC at 25oC (this is a table value and let's assume it doesn't change with temperature).

Then, energy absorbed Q = 27*0.215*(232-22) = 1219.05 cal.
