In a mixture of hydrogen and oxygen gases at the same temperature, which molecules move faster? Why?
They have the same KEnergy.
1/2 masshydrogen*velocityhydrogen^2= 1/2 massO*velocityO^2
velocityH/velocityO= sqrt (massO/massH) as I see it.
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?
