Q1: A horizontal piston/cylinder arrangement is placed in a constant-temperature bath. The piston slides in the cylinder with negligible friction, and an external force holds it in place against an initial gas pressure of 16 bar. The initial gas volume is 0.03 m'. The external force on the piston is reduced gradually, and the gas expands isothermally as its volume triples. If the volume of the gas is related to its pressure so that PV12 is constant, what is the work done by the gas in moving the external force?

Transcribed Image Text:Q1: A horizontal piston/cylinder arrangement is placed in a constant-temperature
bath. The piston slides in the cylinder with negligible friction, and an external force
holds it in place against an initial gas pressure of 16 bar. The initial gas volume is
0.03 m'. The external force on the piston is reduced gradually, and the gas expands
isothermally as its volume triples. If the volume of the gas is related to its pressure
so that PV12 is constant, what is the work done by the gas in moving the external
force?
