1.

A container holds 10^(26) molecules //m^(3), each of mass 3 xx 10 ^-27 Kg. Assume that /6 of the molecules move with velocity 2000 m//s directly towards one wall of the container while the remaining 5//6 of the molecules move either away from the wall or in perpendicular direction, and all collisions of the molecules with the wall are ealastic

Answer»

number of molecules HITTING `1 m^2` of the WALL every SECOND is `3.33 xx 10^28`
number of molecules hitting `1 m^2` of the wall every second is `2 xx 10^29`.
pressure EXERTED on the wall by molecules is `324 xx 10^5 Pa`.
pressure exerted on the wall by molecules is` 4 xx 10^5 Pa`.
