What is an air pressure system?

Chemistry
1 answer:
Anna35 [415]2 years ago
7 0

Answer:

"The number of air molecules above a surface determines air pressure. As the number of molecules increases, they exert more pressure on a surface, and the total atmospheric pressure increases. By contrast, if the number of molecules decreases, so too does the air pressure."
