Two identical cylinders with a movable piston contain 0.4 mol of helium gas at a temperature of 300 k. the temperature of the gas in the first cylinder is increased to 506 k at constant volume by doing work w1 and transferring energy q1 by heat. the temperature of the gas in the second cylinder is increased to 506 k at constant pressure by doing work w2 while transferring energy q2 by heat.
find δeint, 1, q1, and wi for the process at constant volume.

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
