A 100 g aluminum calorimeter contains 250 g of water. The two substances are in thermal equilibrium at 10C. Two metallic blocks are placed in the water. One is a 50 g piece of copper at 84C. The other sample has a mass of 58 g and is originally at a temperature of 100C. The entire system stabilizes at a final temperature of 20C. Determine the specific heat of the unknown second sample.
