How do particles of all matter move?

In constant and random motion.

15

What does Brownian motion describe?

That all particle of matter are constantly moving in a random manner.

15

How does Brownian motion caused?

It is caused by the collision between differnet particles. Example: water particles and pollen grains bumping into each other.

15

How do particles move in a solid?

Unable to move freely, vibrate in fixed positions.
