A hot metal weighing 65.0 g was heated to 125 oC and dropped into 75.0 g of water kept at a room temperature of 20.6 oC in a calorimeter. Within a couple of minutes, water’s temperature increased to 26.8 oC and stayed constant at that temperature. If the heat capacity or calorimetry constant is 11.5 J/oC, find the specific heat capacity of the metal.
