Question
An aluminum pan of mass 100 grams and at a temperature of 375°C is plunged into a vat of water.
a. If the pan and the water end up at 45°C, how much energy did the aluminum pan lose?
b. Assuming no energy goes into the environment, how much energy must the water have gained from the aluminum?

a.
q = mass Al x specific heat Al x (Tfinal-Tinitial)
b.
Look at your specific heat problem just before this as a hint (if you need a hint).
