A copper block is removed from 345°C oven and immediately dropped into 3.75 L of water at 20°C.in an insulated cup. The water quickly reaches 25.35°C and then remains at that temperature. Calculate the following: a) Mass of water in grams b) The heat energy supplied to water by the copper block in joules . (Sp.Heat of water = 4186 J/kg°C) c) The ma of copper block in grams . (Sp.Heat of copper is 385 J/Kg°C)
