A coffee-cup calorimeter of the type shown in Figure 5.18 contains 150.0 g of water at 25.2 °C. A 200-g block of silver metal is heated to 100.5 °C by putting it in a beaker of boiling water. The specific heat of Ag(s) is 0.233J>1g # K2. The Ag is added to the calorimeter, and after some time the contents of the cup reach a constant temperature of 30.2 °C. (a) Determine the amount of heat, in J, lost by the silver block.
