What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure?
well at atmospheric pressure the gas will have a certain density (i'm assuming that you know what density is) when you increase the pressure you push the particles closer together and thus lower the volume of which these particles occupy, and so increasing the pressure increases the density.
As air pressure in an area \(\uparrow\), the density of the gas particles in that area \(\downarrow\)
