3-2) A 2.2 kg block of ice initially at a temperature of -20°C is immersed in a very large amount of liquid
nitrogen (LN) at a temperature of 496°C. and the nitrogen and H20 are allowed to come to thermal
equilibrium [T3p(N2) = -196°C]. Assume energy is exchanged only between H20 and LN. Create a
particular model of this process and use it to determine how much LN is converted to gas (vapor). [The emphasis on “very large" implies that there will still be LN left when the two come to thermal
equilibrium]
