Question

Figure shows the variation of the internal energy U with the density of $\rho$ of one mole of ideal monoatomic gas for a thermodynamic cycle ABCA. Here process AB is part of rectangular hyperbola. Draw P-V diagram for the above process.

Answer 1

Using Ideal gas equation.

$\Rightarrow PV=nRT$

$\Rightarrow P=\rho R$

So, corresponding $P-V$ diagram is
