1. A block of wood measuring 5 m long, 4 m wide and 0.5 m thick is placed on a table. Find the pressure exerted on the table due to the block if the mass of the block is 4000 kg.
2. If the pressure exerted on a floor by a box is 200 kPa, find the weight of the box, given that the bottom of the box has a contact area of 20 $cm^{2}$.
3. Objects of different weights are placed on a rigid, horizontal surface.

Which row shows the correct pressure acting on the surface?
Weight (N)Area in contact ($m^{2}$)Pressure (Pa)
A100.11
B200.20.01
C300.1300
D400.28
4. The diagram shows a glass block resting on a table top.

The area of the block in contact with the table is X and the area of the table top is Y.

The weight of the block is P and the weight of the table is Q.

Which expression gives the pressure exerted on the table by the block?
5. Which of the following does not affect the pressure beneath the surface of a liquid?
6. The diagram shows a simple mercury barometer. Which height is a measure of the atmospheric pressure?

7. A gas is trapped inside a cylinder by a movable piston. The length of the gas column is 50 cm and the pressure inside the cylinder is p.

The piston is pushed in a distance of 30 cm, so that the length of the gas column is now 20 cm. The temperature of the gas does not change.

What is the new pressure of the gas?
8. Four different liquids are poured into identical measuring cylinders. The diagrams show the depths of the liquids and their densities.

Which liquid causes the largest pressure on the base of its measuring cylinder?

pressure at base of cylinder
9. Find the pressure exerted on a person by a few plastic blocks of total mass 42 kg, the bottom of which in contact with the person has an area of 840 $cm^{2}$.
10. A barometer is carried up on a balloon. Why does the reading on the barometer fall?
