Question

What is the relationship between atmospheric pressure and the density of gas particles in an area of decreasing pressure? (2 points)

A. As air pressure in an area decreases, the density of the gas particles in that area decreases.
B. As air pressure in an area decreases, the density of the gas particles in that area increases.
C. As air pressure in an area decreases, the density of the gas particles in that area remains constant.
D. As air pressure in an area decreases, the density of the gas particles in that area increases and decreases in an alternating pattern.

Also it's not showing earth space science, so that's why I put it as Physics.

Answer 1

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

Step-by-step explanation:

At constant temperature, pressure and density of a gas are directly related. So if pressure decreases, density decreases.
