JEE Main Physics Thermodynamics #1 Work Done in a Cyclic Process

Calculate Work for Reversible and Irreversible Expansion/Compression

Thermodynamics - Work Done By a Piston (Quasiequilibrium Processes)

A gas with an initial volume of 0.2 m3 is heated at constant volume, and the pressure increases from 2×105 Pa to 5×105. Then, it compresses at constant pressure until it reaches a final volume of 0.12 m3. Draw the two processes in the PV diagram below and find the total work done by the gas.<img src="https://static.studychannel-prd.pearsonprd.tech/courses/physics/thumbnails/images/ae92fb18"alt=""/>
