Question

State two experiences that make you think that air exerts pressure.(Other than those given in the text).

Answer 1

I think tornadoes and breeze

Answer 2

Two examples of air pressure on the human body

1. When we travel in an airplane, as the plane takes off or when it is landing, we feel pressure inside our ears which sometimes causes pain. This condition is caused by difference of air pressure inside the ear and the pressure outside.  

2. When people go up high altitudes E.g. a mountain, they usually find it difficult to breathe. This is because low pressure in the high altitudes makes it difficult to breathe in air, thereby depriving the body of much needed oxygen.
