At constant temperature, when a bulb $\text{'}\mathrm{A}\text{'}$ of volume $150 \mathrm{mL}$ containing an ideal gas was connected to another evacuated bulb $\text{'}\mathrm{B}\text{'},$ the pressure fell down by $40\%$ of bulb A's initial pressure. Then, find the volume of bulb $\mathrm{B}.$

Calculate the volume occupied by $2.5 \mathrm{g}$ of water vapour at $250{}^{\circ }\mathrm{C}$ and $1$ bar pressure.

Consider the composite system, which is held at $300 \mathrm{K},$ shown in the figure. Assuming ideal gas behavior, calculate the total pressure if the barriers separating the compartments are removed. Assume that the volume of the barriers is negligible. $(\mathrm{R}=0.082 \mathrm{atm}/\mathrm{L}//\mathrm{Mol}.\mathrm{K})$

Calculate the density of ${\mathrm{H}}_2$ gas at $230°\mathrm{C}$ and $6 \mathrm{atm}$ pressure.

An evacuated glass vessel weighs $50 \mathrm{g}$ when empty, $144 \mathrm{g}$ when filled with a liquid of density $0.47 \mathrm{g}·{\mathrm{L}}^{-1}$ and $50.5 \mathrm{g}$ when filled with an ideal gas at $760 \mathrm{mmHg}$ at $300 \mathrm{K}.$ Then find the molar mass of the ideal gas.

At what temperature $($in$K)$, the most probable velocity of ozone gas is equal to RMS velocity of oxygen gas at $t°\mathrm{C}?$

The order of kinetic diameter of ${\mathrm{N}}_2,\mathrm{CO}$ and ${\mathrm{C}}_2{\mathrm{H}}_4$ is:

Given the critical temperature and critical pressure of ${\mathrm{CO}}_2$ gas are $30°\mathrm{C}$ and $72 \mathrm{atm}$ respectively, find the approximate values of Van der Waals constants $\text{'}a\text{'}$ (in $L^2.$ atm. ${\mathrm{mol}}^{-2}$) and $\text{'}a\text{'}$ (in L. ${\mathrm{mol}}^{-1}$).
