430 grams of copper pellets are removed from 330°C oven and immediately dropped into 250 mL of water in an insulated cup. The temperature of water raises 39°C then remains at that temperature. Calculate the following:  a) Mass of water in kilograms b) The heat energy removed from copper pellets in joules . (Sp.Heat of copper is 385 J/Kg°C) c) The initial temperature of water in degree celsius . (Sp.Heat of water = 4186 J/kg°C)
