Q. A hot (70^{circ}C) lump of metal has a mass of 250 g and a specific heat of 0.25 cal/g.^{circ}C. John drops the metal into a 500-g calorimeter containing 75 g of water at 20^{circ}C. The calorimeter is constructed of a material that has a specific heat of 0.10 cal/ g. ^{circ}C. When equilibrium is reached, what will be the final temperature?
