The pressure versus temperature graph of an ideal gas is as shown in Figure 3.82 (a cycle $A BC D$ with $BC$ and $A D$ along lines through the origin). The corresponding density against volume graph will be:

Options:

Answer:

Solution:

$BC$ and $A D$ are isochoric, so density and volume do not change in them. For a fixed mass $ρ V = m$ , so every state lies on one hyperbola $ρ \propto \frac{1}{V}$ . $A B$ and $C D$ move along it. B.
