A plot of volume of the gas Versus $\mathrm{T}\left(\mathrm{K}\right)$ is shown below. Which of the options is correct for the plot?

$1 \mathrm{L}$ each of gases $\mathrm{A}$ and $\mathrm{B}$ diffused through a membrane in $15$ and $30$ minutes, respectively, under identical conditions. What is the ratio of molecular weight of $\mathrm{A}$ and $\mathrm{B}?$

The figure represents $\mathrm{PV}$ vs $\mathrm{P}$ relation for $\mathrm{CO},{\mathrm{CH}}_4,{\mathrm{H}}_2$ and $\mathrm{He}$ gases under identical conditions. Which curve, shown in the figure, represents $\mathrm{He}$ gas?

Which gas has a density of $1.24 \mathrm{g}/\mathrm{L}$ at $0{}^{\circ }\mathrm{C}$ and $1 \mathrm{atm}$ pressure?

The most probable velocity of a gas at $7200 \mathrm{K}$ is equal to the RMS velocity of $\mathrm{He}$ gas at $27°\mathrm{C}.$ The gas is

How many times the volume of a diatomic gas should be increased reversibly and adiabatically in order to reduce its RMS velocity to half of its intial value.

The ratio of rates of diffusion of oxygen and an unknown gas is $1: 4$. The unknown gas is

Two gases $\mathrm{A}$ and $\mathrm{B}$ are released from the two ends of a tunnel of length $100 \mathrm{m}$. A travels $40 \min$, before meeting the gas $\mathrm{B}$ in the tunnel. If the molecular weight of $\mathrm{B}$ is $18$ , what is the molecular weight of $\mathrm{A}$ ?
