Answer #1

Using Ideal gas equation,

PV = nRT

P1 V1/n1 R T1 = P2 V2/n2 R T2

P2 = P1 (n2 T2)/(n1 T1)

P2 = [(100 - 40.9) x 277.1 x 4370]/(100 x 296.9)

P2 = 2410.43 kPa

    A bottle at 317 K contains an ideal gas at a pressure of 150 kPa. The rubber stopper closing the bottle is removed. The gas expands adiabatically against Pext = 107 kPa, and some gas is expelled from the bottle in the process. When P = Pext, the stopper is quickly replaced. The gas remaining in the bottle slowly warms to 317 K. What is the final pressure (in kPa) in the bottle for a monatomic gas for which CV,m...
