1. In an experiment, the volume of a fixed mass of gas is decreased by trapping the gas at the top of a glass tube with a quantity of oil and then using a pump to push the oil up the tube.
\nThe pressure of the gas is measured with a Bourdon gauge and the volume of gas is measured using a calibrated scale next to the glass tube. The results are shown.<\/p>\n

\"\"<\/a><\/p>\n

(a) Draw a rough graph (no values needed) of volume against 1 \/ pressure.<\/p>\n

(b) What does this graph tell you about the relationship between the volume and pressure of a fixed mass of gas?<\/p>\n

(c) Explain this relationship in terms of the kinetic theory of particles.<\/p>\n

2. Explain, using the appropriate gas law, why a balloon will burst if you squeeze it.<\/p>\n

3. A 5 cm3<\/sup> syringe is filled with air and the pressure of the air is found to be 1.01 x 105<\/sup> Pa. The syringe plunger is then pushed until there is 3 cm3<\/sup> of air. What is the new air pressure?<\/p>\n

4. A scuba diving air tank has a volume of 7.5 litres and is filled with air at a pressure of 1.21 x 107<\/sup> Pa. \"\"<\/a>What volume of air will be released by the tank at atmospheric pressure (1.01 x 105<\/sup> Pa)?<\/p>\n","protected":false},"excerpt":{"rendered":"
