So the collisions change the momentum of the individual molecules all the time, but the average stays the same - and the individual molecules are far more likely to change momentum to be closer to the average than not. | |

A gas centifuge increases the weights by increasing the acceleration. Gases can also have negative weight (weight is a Vector force properly expressed in Newtons), and all fluids can have thermoclines, open a refrigerator on a moist day and atmospheric gas is seen to visibly spill onto the floor. But the box explanation is very good because it is a "control" example. Bear in mind results depend upon the wieght of the fluid you are displacing, an Archimedian concept. | |
