a 200g peice of metal at 19C is added to 80g of water at 60C in a styrofoam cup(for insulation). the temperature of the water is cooled at 54.7C. Find the temperature for the water and the metal. Assume that the final temperatures for the water and the metal are the same. make sure to use the correct sign
