2.0 g of $\mathrm{H}_2$ diffuses through a porous container in 10 minutes. How many grams of $\mathrm{O}_2$ would diffuse from the same container in the same time under similar conditions?

At $T(\mathrm{~K})$, the $u_{\mathrm{rms}}$ of $\mathrm{CO}_2$ is $412 \mathrm{~ms}^{-1}$. What is its kinetic energy (in $\mathrm{kJ} \mathrm{mol}^{-1}$ ) at the same temperature ?

$$ \left(\mathrm{CO}_2=44 \mathrm{u}\right) $$

Identify the correct graph for an ideal gas $(y$-axis $=$ compressibility factor, $Z: x$-axis $=$ pressure, $p)$

Identify the correct statements from the following:

I. Glass is an extremely viscous liquid.

II. Increase in temperature decreases the surface tension of liquids.

III. Compressibility factor for an ideal gas is zero.
