  • don't different gasses have varying densities? If one gas is of one density and another is of another density, if you add both gasses together you wouldn't necessarily get the sum of both gasses pressures as the densities mix and create a average pressure.

  • @Wressnigg Yes they do and that value is incorporated into the percentages and sure they can fluctuate but minimally at varying temperatures, but not enough to the point of creating an average pressure. Average pressure insinuates that they ALL share similar amounts of pressure. But how can a gas such as CO2 in the environment which constitutes for less than 1% contribute evenly to the pressure as would N2 which the atmosphere contains about ~79%. Do you see what I'm getting at?

  • thank you very much
