As shown on the right, a vertical piston–cylinder assembly containing a gas is placed on a hot plate. The piston initially rests on the stops. With the onset of heating, the gas pressure increases. At what pressure, in bar, does the piston start rising? The piston moves smoothly in the cylinder and g = 9.81 m/s2.

As shown in the figure below, air is contained in a vertical piston-cylinder assembly such that the piston is in static equilibrium. The atmosphere exerts a pressure of 14.7 lbf/in.² on top of the 6-in.-diameter piston. The absolute pressure of the air inside the cylinder is 20 lbf/in.². The local acceleration of gravity is g = 32.2 ft/s². Determine the mass of the piston, in lb. Mpiston = Determine (a) the mass of the piston, in lb, and (b) the gage pressure of the air in the cylinder, in psig. lb p(gage) = i Pa 14.7 lbf/in.² g=32.2 fus² Determine the gage pressure of the air in the cylinder, in psig. psig Di Air Pair
