1. The diagram shows a simple mercury barometer. Which height is a measure of the atmospheric pressure?

2. Which of the following does not affect the pressure beneath the surface of a liquid?
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. A manometer is connected to a gas supply.

pressure qn 2Pressure can be measured in cm of water.

What is the pressure of the gas?
5. 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
6. A gas occupies a volume of $2.0 \text{ m}^{3}$ in a cylinder at a pressure of 240 kPa. A piston compresses the gas until the volume is $0.50 \text{ m}^{3}$, the temperature remaining constant.

What is the new pressure of the gas?
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. 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?
9. A barometer is carried up on a balloon. Why does the reading on the barometer fall?
10. A small table weighing 40 N stands on four legs, each having an area of $0.001 \text{ m}^{2}$. What is the pressure of the table on the floor?

  1. How The question no.6 answer is 2000 pascal?
    Its supposed to be 200 pascal, with the rule .
    P=F/A
    P=4000/5×4
    = 4000/20
    =200.

    How 2000?
