A 12.9-g sample of an unknown metal at 26.5° is placed in a Styrofoam cup containing 50 g of water at 88.6°. The water cools down, and the metal warms up until thermal equilibrium is achieved at 87.1°. Assuming all the heat released by the water is absorbed by the metal and that the cup is perfectly insulated, determine the specific heat of the unknown metal. The specific heat of water is4,186 J/(kg ·K).
