Question

S8. Why is the folloruing situation impossibler An apparatus is designed so that steam initially at T-150°C, P= 1.00 atm. and V-0.500 m in a piston-cylinder apparatus under- goes a process in which (1) the volume remains constant and the pressure drops to 0.870 atm, followed by (2) an expansion in which the pressure remains constant and the volume increases to 1.00 m, followed by (3) a return to the initial conditions. It is important that the pressure of the gas never fall below 0.850 atm so t he piston will support a delicate and very expensive part of the appara- tus. Without such support, the delicate apparatus can be severely damaged and rendered useless. When the design is turned into a working prototype, it operates perfectly
