5.9 understand the significance of Brownian motion, as supporting evidence for particle theory

Brownian motion is the principle that particles move randomly about a space.
Particle theory says that as particles move about (randomly) they collide, when they collide with a surface the exert a pressure on the surface (like air keeping a balloon inflated.)

    thankyou for your blog! i was wondering if you knew how we can use this idea to explain pressure in gases?

    I'd just like to add that Brownian motion ONLY occurs in fluids (gases+liquids)
