The piston of a vertical piston-cylinder device containing a gas has a mass of 40 kg and a cross-sectional area of 0.012 m2 . The local atmospheric pressure is 95 kPa, and the gravitational acceleration is 9.81 m/s2 (a) Determine the pressure inside the cylinder. (b) If some heat is transferred to the gas and its volume is doubled, do you expect the pressure inside the cylinder to change? Patm = 95 kPam = 40 kg'A=0.012 m2

The free-body diagram of the piston can be drawn as follows,

Answered: Patm = 95 kPa m = 40 kg 'A= 0.012 m2
