1-60 The piston of a vertical piston-cylinder device containing a gas has a mass of 60 kg and a cross-sectional area of 0.04 m², as shown in figure. The local atmospheric pressure is 0.97 bar, 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? [1.12 bar] Value (7/20) P. atm = 0.97 bar m = 60 kg A = 0.04 m² P = ?
