Consider a Mixture of Oxygen and Hydrogen Kept at Room Temperature. as Compared to a Hydrogen Molecule an Oxygen Molecule Hits the Wall - Physics


Consider a mixture of oxygen and hydrogen kept at room temperature. As compared to a hydrogen molecule an oxygen molecule hits the wall


  • with greater average speed

  • with smaller average speed

  • with greater average kinetic energy 

  • with smaller average kinetic energy

with smaller average speed

The average speed of molecules is given by \[\sqrt{\frac{8kT}{\pi m}}\] .

We observe that greater the mass, lesser is the average speed of the molecule. Since an oxygen molecule is heavier than a hydrogen molecule, the oxygen molecule will hit the wall with smaller average speed.

  Is there an error in this question or solution?
