Given are the following four containers.

(I) ${\mathrm{H}}_2\left(\mathrm{g}\right)$

(II) $\mathrm{He}\left(\mathrm{g}\right)$

(III) $N_2\left(g\right)$

(IV) ${\mathrm{O}}_2\left(\mathrm{g}\right)$

Each container contains the same mass of the indicated gas at the same T ( = 300 K). Based on this information, answer the questions given below.

The container having a gas with minimum viscosity is
