Question

Match the thermodynamic conditions: P: volume change is zero; Q: pressure is constant; R: no heat is exchanged; S: work done by gas equals heat supplied. Column-II: (i) ΔW=0, (ii) ΔQ=0, (iii) Isobaric, (iv) Isothermal.

P is isochoric, so ΔW=0 → (i). Q is isobaric → (iii). R is adiabatic, so ΔQ=0 → (ii). If heat supplied equals work done, ΔU=0 and for an ideal gas ΔT=0, hence isothermal → (iv).
