A container holds$10^{26}$molecule/$m^3$, each of mass$3\times 10^{-27}$kg. Assume that$\frac{1}{6}$of the molecules move with velocity 2000 m$s^{-1}$directly towards one wall of the container while the remaining$\frac{5}{6}$of the molecules move either away from the wall or in a perpendicular direction, and all collisions of the molecules with the wall are elastic:
