Which of the following statements is an effect of compressing gas molecules at constant temperature?
- The pressure on the molecules decreases.
- The molecules gain more kinetic energy.
-
The molecules make more impact per second on the walls of the container.
- The molecules increase in size.
The correct answer is: 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.
