Consider two 35-gram ice cubes, each initially at -5°C. One is dropped into a at container filled with 0.1 kg of liquid nitrogen (initially the boiling point of nitrogen); the other cube is dropped into a container filled with 1 kg of (liquid) water, initially at 5°C. Assume that no heat is lost through either container (or into the atmosphere)

a) Describe what happens to each ice cube (and why)

b) If (Lv)Nitrogen =48 kcal/kg, (LF)Nitrogen = 6.1 kcal/kg, and cNitrogen =0.15 kcal/(kg °C), determine how much heat would be needed to produce 100 grams of nitrogen gas at 20°C.

c) Determine the final (equilibrium) temperature of the icewater mixture.

d) Determine the phase (ie., liquid or solid) corresponding to the equilibrium temperature you obtained in part (c).
