Physics - Gravitation Question with Solution | TestHub

During an experiment, an ideal gas is found to obey a condition $\frac{{\mathrm{P}}^2}{\rho }=\mathrm{constant}$ ( P is pressure and $\rho$ is the density of gas). The gas is initially at temperature $T_0$, pressure $P_0$ and density $d$. The gas expands such that density changes to $d/2$. Then,
