What causes Brownian motion?
Brownian motion involves lighter particles like air molecules colliding with heavier particles like smoke, causing the heavier particles to move around randomly.

What causes diffusion?
Random motion of particles causes diffusion. Particles randomly move around and collide, causing them to spread from areas of high concentration to areas of low concentration until evenly dispersed.

What happens to particle motion when temperature increases?
At higher temperatures, particles have more kinetic energy so they move quicker and collide more forcefully.

What effect does increased particle movement have on pressure?
There is increased particle collision with container walls, increasing the pressure.
