1.

The 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.

2. 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?

3. 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 $cm^{2}$.

4. A manometer is connected to a gas supply.

Pressure can be measured in cm of water.

What is the pressure of the gas?

5. A barometer is carried up on a balloon. Why does the reading on the barometer fall?

6. Which would be the least likely to sink into soft ground?

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

What is the pressure of the gas in the cylinder?

8. 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 $cm^{2}$.

9. 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.

10. Bubbles of gas, escaping from the mud at the bottom of a deep lake, rise to the surface.

As the bubbles rise, they get larger.

Why is this?

1. how can i get the answers….

2. I think here, in question 9 the answer (a) shall be
5.0 x 10^-3
5.0 x 10^3

• Can you show how you arrive at $5.0 \times 10^{-3}$?

3. physics
