In a purity check for industrial diamonds, a 20.25 - carat (1 carat = 0.2000 g) diamond is heated to 80.5 °C and immersed in 30.1 g of water in a constant-pressure calorimeter. The initial temperature of the water is 28.0 °C. Calculate AT of the water and of the diamond (heat capacity of diamond = 0.519 J/g • K).
