1. Liquid nitrogen at −196° C (nitrogen’s boiling point) is placed in a container with 3 kg of water at 25° C. (a) Suppose you add just enough liquid nitrogen such that all the water just freezes (i.e., the final state of the water is ice at 0° C). Draw a complete energy interaction diagram for this scenario, including a conservation of energy equation. (b) How much liquid nitrogen should you put in the container such that all the water...
