7. What happens to the air pressure in an area

when a cold air mass becomes denser?

A. The air pressure reverses.

B. The air pressure increases.

C. The air pressure decreases.

D. The air pressure stays the same

Option B. The air pressure increases.

Explanation:

The air pressure of warm and cold air is different from one another because in warm air, the distance between molecules is high and there is maximum empty spaces so the air pressure is also lower while in cold air, the distance between particles are very low and there is less empty spaces so due to denser medium the air pressure also increases.
