Question

$P-V$ diagram of an ideal gas for a process $ABC$ is as shown in the figure. Plot pressure versus density graph of the gas for the process $ABC$.

Answer 1

Process $AB$ : Pressure is constant while volume decreases hence in this process $AB$ density increases from ${\rho }_{0}to$ $3{\rho }_0$ as $\rho =mass/density$.
Process $BC$ : Volume is constant(density constant) while pressure increases from $P_0$ to $3P_0$
