According to the kinetic theory of gases, the pressure exerted by a gas is due to

  1. The weight of the gas particles.
  2. The attractive forces between gas particles.
  3. The collisions of gas particles with the container walls. ✓
  4. The vibrations of gas particles.

Explanation

Gas pressure comes from particles hitting container walls. Each collision pushes on the wall. Millions of collisions create the pressure we measure.

Weight pulls down, not sideways. Gas particles barely attract each other. Vibrations happen in solids, not gases.

Remember: More collisions equal higher pressure. Faster particles also create more pressure.
