1. The diagram shows the levels X and Y in a liquid manometer when the gas tap is opened.

gas pressure qnWhat is the pressure of the gas in the cylinder?
2. 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
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 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.
5. Which graph shows the relationship between the pressure and volume of a fixed mass of gas at constant temperature?

pressure qn1

6. 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.
7. CYLINDERThe diagram above shows a cylindrical container with diameter 0.5 m containing a liquid of density 750 $kg \, m^{-3}$. Find the pressure exerted by the liquid on the base of the container.
8. Which of the following will cause the height of the mercury column in a barometer, A, to be higher than  that of another barometer, B, located at sea level?
9. 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?
10. 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 $cm^{2}$.
