A 2.60 multiplied by 102 kg cast-iron car engine contains water as a coolant. Suppose that the engine's temperature is 35.0°C when it is shut off and the air temperature is 10.0°C. The heat given off by the engine and water in it as they cool to air temperature is 4.5 multiplied by 106 J. What mass of water is used to cool the engine?
