In a mixture of hydrogen and oxygen gases at the same temperature, which molecules move faster? Why?

  • science -

    They have the same KEnergy.

    1/2 masshydrogen*velocityhydrogen^2= 1/2 massO*velocityO^2

    velocityH/velocityO= sqrt (massO/massH) as I see it.

  • science -

    K. E. = 1/2*mass*velocity2
    At the same temperature, both gases have the same kinetic energy (K.E.). Knowing that and the masses, what must be true of the velocity?
