Question

What would happen to the air pressure on Earth's surface if the density of Earth's atmosphere were to suddenly double?A. The air pressure would decrease by half. B. The air pressure would increase 2X. C. The air pressure would stay the same. D. The air pressure would increase 4X.

Answer 1

Answer:

B. The air pressure would increase 2X

Explanation:

Pressure = density × acceleration due to gravity × height

p = ρ × g × h

Pressure is force per unit area

p = F/a

Density is mass per unit volume

Pressure is directly proportional to density hence, any change in the density of a body directly affects the change in pressure of the body and vice versa.
