Detailed Solution
Process AB is an isothermal process, i.e., P∝1/V and since ρ∝1/V,ρ−V graph will be a rectangular hyperbola. Pressure is increasing; therefore, volume will increase. Process BC is an isochoric process. Therefore, V = constant and since ρ = m/V, density is also constant, i.e., ρ -V graph is a dot. Process CD is inverse of process AB and process DA is inverse is BC.
