Question 2
2 marks · Easy
Answer and see the solution →Explain, using the particle model, why the pressure of a gas increases if it is compressed into a smaller volume at constant temperature.
Question 3

Answer and check →Which of the following statements about Boyle's law is correct?
- A.The pressure and temperature of a gas are inversely proportional at constant volume.
- B.The volume of a gas decreases as its pressure increases, at constant temperature.
- C.The volume of a gas increases as its pressure increases, at constant temperature.
- D.The mass of a gas must change for Boyle's law to apply.
Question 4
2 marks · Easy
Answer and see the solution →A balloon filled with gas is left in a warm room. Answer the following questions.
(a)[1 mark]State what happens to the average kinetic energy of the gas molecules as the temperature of the room increases.
(b)[1 mark]Explain how this affects the motion of the gas particles.
Question 5
1 mark · Easy
Answer and see the solution →According to the particle model, what causes the pressure of a gas in a sealed container?
Question 6
2 marks · Easy
Answer and see the solution →A gas in a sealed syringe has a pressure of 80 kPa and a volume of 25 cm³ at constant temperature. What will its pressure be if the volume is reduced to 20 cm³? Give your answer to 2 significant figures.
Question 7
1 mark · Easy
Answer and see the solution →Give the relationship between the average kinetic energy of gas molecules and the temperature of the gas.
Question 8
1 mark · Easy
Answer and see the solution →Name one way to change the pressure of a fixed mass of gas inside a sealed container (other than changing its volume).
Question 9
2 marks · Normal
Answer and see the solution →State Boyle's law in terms of the relationship between the pressure and volume of a fixed mass of gas at constant temperature.
Question 10
3 marks · Normal
Answer and see the solution →Explain, in terms of the particle model, why increasing the temperature of a gas at constant volume increases the pressure of the gas.
