Which one of the following graphs is not correct for an ideal gas?
$d =$ Density,$P =$ Pressure,$T =$ Temperature

At $27\,^oC$ temperature,$4\,mol$ $Cl_2$,$4\,mol$ $N_2$,and $2\,mol$ $O_2$ are filled in a $5\,L$ closed vessel. Find the total pressure of the gaseous mixture. $(R = 8.34 \times 10^{-2} \,bar \,L \,mol^{-1} \,K^{-1})$ (in $,bar$)

For an ideal gas,which of the following graphs will not be a straight line?

At $273 \ K$ temperature and $76 \ cm \ Hg$ pressure,the density of a gas is $1.964 \ g \ L^{-1}$. The gas is

If two identical containers $X$ and $Y$ containing $O_2$ gas are subjected to expansion from volume $V$ to $2V$ under identical isothermal conditions by applying pressure changes of $\Delta P$ and $0.2 \Delta P$ respectively,then the ratio of the mass of $O_2$ gas in container $X$ to container $Y$ is

Which effect is observed when the pressure of a gas increases?
