Problem

10^{22}

gas molecules each of mass

10^{-26} \text{ kg}

collide with a surface (perpendicular to it) elastically per second over an area

1 \text{ m}^2

with a speed

10^4 \text{ m/s}

, the pressure exerted by the gas molecules will be of the order of: (1)

10^4 \text{ N/m}^2

(2)

10^8 \text{ N/m}^2

(3)

10^3 \text{ N/m}^2

(4)

10^{16} \text{ N/m}^2
