pressure of the gas

1.24   The pressure of the gas contained in the piston–cylinder assembly of Fig. 1.1 varies with its volume according to p 5 A 1 (B/V), where A, B are constants. If pressure is in lbf/ft2 and volume is in ft3, what are the units of A and B?

 

1.25   As shown in Figure P1.25, a gas is contained in a piston– cylinder assembly. The piston mass and cross-sectional area are denoted m and A, respectively. The only force acting on the top of the piston is due to atmospheric pressure, patm. Assuming the piston moves  smoothly  in  the  cylinder  and the local acceleration of gravity g is constant, show that the pressure of the gas acting on the bottom of the piston remains constant as gas volume varies. What would cause the gas volume to vary?
