JEE AdvancedPhysicsHeat and ThermodynamicsMCQ+3 / −1
A gas is enclosed in a cylinder with a movable frictionless piston. Its initial thermodynamic state at pressure Pi = 105 Pa and volume Vi = 10-3 m3 changes to a final state at Pf = (132)×105 Pa\left( {{1 \over {32}}} \right) \times {10^5}\,Pa(321​)×105Pa and Vf = 8 ×\times× 10-3 m3 in an adiabatic quasi-static process, such that P3V5 = constant. Consider another thermodynamic process that brings the system from the same initial state to the same final state in two steps: an isobaric expansion at Pi followed by an isochoric (isovolumetric) process at volume Vf. The amount of heat supplied to the system in the two-step process is approximately
