  • A The pressure on the molecules decreases.
  • B The molecules gain more kinetic energy.
  • C The molecules make more impact per second on the walls of the container.
  • D The molecules increase in size.
Correct Answer: Option C
Explanation:
More collisions mean more force, so the pressure will increase.
When the volume decreases, the pressure increases.
This shows that the pressure of a gas is inversely proportional to its volume.
This is shown by Boyle's law.
