1. A manometer is connected to a gas supply.

Pressure can be measured in cm of water.

What is the pressure of the gas?
2. 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?
3. An air bubble is inside a air-tight cylinder fitted with a piston. What happens to the air bubble when the piston is pushed in? Note that the air bubble is surrounded by air in the cylinder. Assume that the there is still enough space for the air bubble to "survive" after the piston is pushed in.
4. The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water.

Which one of the following statements is correct?
5. Air is trapped in a cylinder by a piston. The pressure of the air is $\rho$ and the length of the air column is 20 cm.

The piston is moved outwards until the length of the air column has increased by 40 cm.

The temperature of the air remains constant.

What is the new air pressure?
6. 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 $cm^{2}$.
7. The diagram shows a simple mercury barometer. Which height is a measure of the atmospheric pressure?

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. Which of the following does not affect the pressure beneath the surface of a liquid?
10. 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?

    • @Aisha
      You have to answer the quiz and you will get the correct answers upon the submission of the answers you gave to the questions.

    • Click on “I am not a robot” which is at the bottom section of the page.
      Then click “Submit”.
      And the checked page will be opened.
