Which best explains why increasing the pressure on a gas decreases the volume of the gas sample?

• Increasing the pressure causes the gas particles to hit the container walls more often.

• Increasing the pressure on a gas sample moves the gas particles closer together.

• Increasing the pressure on a gas sample causes the kinetic energy to increase.
