    Can anyone answer mine this.
    A flask contains a mixture of gases, all of which may be assumed to be ideal. Suggest why all the molecules have the same KE but the distribution of speeds for the molecules of each gas will be different.

    Thanks

    I think I got it actually, its just to do with the different masses of the molecules?

    Average Ke is constant because average Ke is temperature dependant
    Larger masses will tend to travel slower to keep average Ke the same
