One mole of a monatomic ideal gas undergoes four thermodynamic processes as shown schematically in the $$PV-diagram$$ below. Among these four processes, one is isobaric, one is isochoric, one is isothermal and one is adiabatic. Match the processes mentioned in $$List-1$$ with the corresponding statements in $$List-II$$.

$$Process-I$$ is an adiabatic processΔ$$Q=$$Δ$$U+W$$      Δ$$Q=0$$            $$W=$$−ΔU     Volume of gas is decreasing    ⇒W<$$0$$   ΔU>$$0Temperature$$ of gas increases No heat is exchanged between the gas and surrounding.Process –II is an isobaric process (pressure$$ remain $$constant)W=P$$Δ$$V=3P03V0$$−$$V0=6P0V0$$ $$Process-III$$ is an isochoric process $$($$ volume remain $$constant) Δ$$Q=$$Δ$$U+W$$         ⇒Δ$$Q=$$ΔU  $$Process-IV$$ is an isothermal process (temperature$$ remains $$constant)Δ$$Q=$$Δ$$U+W$$ ⇒Δ$$U=0$$
