Question

Which of the following statements is most accurate?

A.) Warm air sinks
B.) Warm air is denser than cold air
C.) Warm air is less dense than cold air
D.) Warm air exerts more pressure on the land than cold air

Answer 1

Answer: Option C) Warm air is less dense than cold air

Explanation:

Due to greater temperature of warm air than cold air, the space between intermediate molecules is more as compared to cold air. It means the warm air expands. Hence, the density of warm air is less than cold air. On the other hand, the cold air comparatively denser and sinks. Warm air is lighter and rises.

Thus, correct option is C) Warm air is less dense than cold air.
