Case Study Questions for Class 8 Science Chapter 11 Force and Pressure

Here we are providing case study questions for CBSE Class 8 Science Chapter 11 Force and Pressure.

Case Study Questions

Question 1:

Read the passage and answer the following questions

The discovery of atmospheric pressure gives a fact that air has weight. The weight of the atmosphere presses down on the earth’s surface and creates pressure on it. The pressure at any point exerted by the weight of the air above is called atmospheric pressure.
The atmospheric pressure on the earth’s surface at sea level is one hundred thousand pascals i.e., 100 KPa. The atmospheric pressure at a place decrease with an increase in altitude. The atmospheric pressure at a place is the force exerted by the weight of the air column above that place. As we go up the length of the air column above us decreases. This means that its weight and the atmospheric pressure are smaller at higher places than at sea level. If the pressure of the atmosphere is removed suddenly, our blood vessels and tissues will rupture due to the pressure of the blood and other fluids inside. Thus, the spacemen also wear special pressurised suits as in space there is no air and hence, no air pressure. At the top of a mountain, some people can feel their ears “popping” due to a decrease in air pressure. The ears pop to balance the difference in pressure inside and outside the body.

Answer the questions given below:

a) What is atmospheric pressure?
b) We know that there is a huge amount of atmospheric pressure on us. But we do not experience its effect. Why?
c) Why do some people feel their ears “popping” at the top of the mountain?

Answers

a) The pressure exerted by the air around us is known as atmospheric pressure.

b) The pressure of the air inside our body is the same as that of the pressure outside. Therefore, we do not experience its effect.

c) Some people feel their ear-popping at the top of the mountain due to the decrease in the air pressure. The ears pop to balance the difference in pressures inside and outside of the body.
