A 350g sample of aluminum is taken out of the freezer at –20oC and placed into 500g of water at 14.6 oC.  If the water and the aluminum both end up at 10 oC, what is the specific heat of aluminum? hint: since the heat lost by the water equals the heat gained by the aluminum, you can set up the equation as follows:  mass water × ΔTwater × C water = - mass metal × ΔTmetal × c metal
