What is the pressure exerted by 10^(23) gas molecules, each molecule of mass 10^(-23)g, present in a container of volume one L and RMS speed of 1000 m s^(-1)?

Answer»

Solution :KINETIC GAS equation `PV = (1)/(3) mnC^(2)`
Pressure of the gas (P) ` = (mnC^(2))/(3V) = (10^(-23) xx 10^(23) xx 10^(10))/(3 xx 1000) = 3.33 xx 10^(8)` dyne `cm^(-2)`
