Question

a) Air occupies space

b) Air is a mixture of gases

c) Air exerts pressure

d) None of the above​

Answer 1

Answer:

c) air exerts pressure

Answer 2

Option (c): When the wind blows, the leaves of trees, banners, and flags flutter because air exerts pressure.

Explanation:

• The pressure imposed by moving air or wind causes the leaves of trees, flags, and banners to flutter when the wind blows. The objects it comes into contact with are subjected to a force or pressure from moving air or wind.
• The atmosphere is the air envelope that encompasses the entire planet. Air has a weight to it. The weight of air is constantly exerted upon our bodies.
• The weight of air acting on a surface causes air pressure.
