The given graph shows four different processes (adiabatic, isothermal, isobaric, and isochoric) for an ideal gas starting from the same initial state. Study the graph carefully and state which statement is correct:
Show Hint
Remember these simple geometric rules for $P-V$ plots: Vertical line = Isochoric (constant volume), Horizontal line = Isobaric (constant pressure). This allows you to identify Path 1 as isochoric and choose Option (C) right away.
