The cyclic process from X to Y is an isothermal process.
If the pressure of the gas at X is 4.0 kPa, and the volume is 6.0 m3, and if the pressure at Y is 8.0 kPa, what is the volume of the gas at Y?
Given : Px=4.0 kPa
Vx=6.0 m3
Py=8.0 kPa
X to Y is an isothermal process, thus temperature remains constant, i.e T=constant or PV=constant
⟹ PyVy=PxVx
⟹ 8.0×Vy=4.0×6.0
⟹Vy=3.0 m3
