The heavier particles sinks to them bottom and "refuses" lighter particles to hang out around much. They manage to push the lighter particles to off-the-ground spaces, and the average velocity of lighter and heavier, these two types of particles, differs by about 2 fold or more.
In this zoomed photo, the greyish particles mentioned in earlier blog entry have more visibility on them.
As a reminder, here are the data/info on the particles and on this experiment:
White particles are 1 mass unit each, while grey particles are 2.2 roughly mass unit each. Both of them are circular, the white particles have smaller radius. The wall and everything in the experiment is elastic, and the space between the particles are technically vacuum space. Elastic means there will be no absorbtion of momentum from collisions whatsoever. The friction of any objects in this experiment are also zero.
Here we can see that the lighter particles (white particles) occupy the top atmosphere mostly, while at middle section, it's a misture, and they become lesser percentage of total number of gas particles closer at the bottom. The heavier particles manage to remain in the lesser high altitude layer with assistance from an invisible force - the conservation of momentum equation. It causes the heavy particles to be ones with lesser velocity while the lighter particle would obtain higher velocity. Whenever a collision between white and grey particle occurs - the greyish on average loses its velocity while the lighter ones gain velocity. This gives additional contribution to the seperation of them in different layers - the top layer gets only ocupied by light particles as we see here since not only do the heavier ones are too heavy to go there, also because no other particle can launch it to that height through collisions. The underlying works of nature again demonstrates to us the wonderful nature of nature itself. There will be much more release of finds - a lot more to come
