Transcribed Image Text:Current Attempt in Progress
As shown in the figure below, a piston-cylinder assembly contains
20 g of air holding the piston against the stops, where the mass of
the piston is 150 kg. The air, initially at 3 bar, 600 K, is slowly cooled
until the piston just begins to move downward in the cylinder. The
air behaves as an ideal gas, g = 9.81 m/s2, and friction is negligible.
Patm = 1 bar
