Q21. Consider a mixture of oxygen and hydrogen kept at room temperature. As compared to a hydrogen molecule an oxygen molecule an oxygen molecule hits the wall (a) with greater average speed (b) with smaller average speed (c) with greater average kinetic energy (d) with smaller average kinetic energy
Considering the Vrms when the gas molecule are at room temperature
Vrms=(3KT/m)^1/2
Hence, V is inversely proportional to m of the gas
and we know that
m of oxygen > m of h...
