1.A thermodynamical system is changed from state (P1,V1)(P_1, V_1)(P1,V1) to (P2,V2)(P_2, V_2)(P2,V2) by two different processes, the quantity which will remain same will bea.ΔQ\Delta QΔQb.ΔW\Delta WΔWc.ΔQ+ΔW\Delta Q + \Delta WΔQ+ΔWd.ΔQ−ΔW\Delta Q - \Delta WΔQ−ΔWLogin to continueOnly logged in users canattempt or see the solution.
