A 0.958 kg block of copper initially at 30.0oC, is dropped into an insulated container with a large quantity of liquid nitrogen. The liquid nitrogen is at its boiling point, -195.8oC. As the copper block cools to the temperature of the liquid nitrogen, -195.8oC, some of the nitrogen will boil away. What is the mass of the nitrogen that boils away? Use 390 J/kg?Co as the specific heat of copper and 200 kJ/kg as the heat of vaporization of nitrogen.
