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...
