Pleases help me thanks.
5 kg of liquid water at 100°C was converted to steam at 100°C by boiling at standard atmospheric pressure, in the arrangement of the figure below. The volume of the water changed from an initial value of 0.005 mº as a liquid to 8.355 mº as steam. Latent heat of vaporization for water Lv = 2256 kJ/kg. Standard atmospheric pressure is 1 atm or 1.01 x 109 Pa. Loaded Piston Steam Insulation Insulation Liquid water Thermal...

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...
