What is the relationship between atmospheric pressure and the density of gas particles in an area of decreasing pressure?

As air pressure in an area decreases, the density of the gas particles in that area decreases.

As air pressure in an area decreases, the density of the gas particles in that area increases.

As air pressure in an area decreases, the density of the gas particles in that area remains constant.

As air pressure in an area decreases, the density of the gas particles in that area increases and decreases in an alternating pattern.

  1. well, I do not think you need anything but imagination here but anyway
    if
    PV = n R T

    density proportional to n/V

    n/V = P/RT
    if T constant
    density goes down if pressure goes down
