Question

1) A block of iron at Tiiron- 500°C is placed on top of a block of ice (solid water) at Ti water-50°C in an insulating container so no heat can be transferred into or out of the container. Parts of the graphs of Tvs energy added for the three-phase model are shown to the right. Use these graphs to find the approximate final equilibrium temperatures, Tf iron and Tfwater, the final phases of the iron and water, and the approximate total heat transferred in the process. Explain your answers using conservation of energy ideas and the graphs. The temperature scales are slightly different so be careful TO C) iron block initial oint 400 200 solid phase Energy Added (kJ) vapor phase ice block 100 TOC) 50 liquid phase initial 0 point solid phase 10 Energy Added (kJ)

    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...
