GCSE Questions: Kinetic Theory - Gases

Q3. Ringo used the equipment shown in the diiagram to investigate how the pressure of a gas varies with the volume of the gas.

The syringe is filled with air.

Here is a table of the results:

Volume /cm3
Pressure /kPa
24
100
20
120
12
200
10
240

 

(a) Describe how Ringo could have used the equipment shown above to obtain the data shown in the table.

[4 marks]

(b) Describe what happens to the pressure of the air when the volume of the air is halved.

[2 marks]

(c) The temperature of the air in the syringe remained constant during Ringo's investigation.

Tick two properties of the air particles listed in the table below that would change if the temperature increased.

kinetic energy  
mass  
shape  
speed  
volume
