Question

brownian motion is caused by the collision of molecules.​

Answer 1

Answer:

follow me on brainly

Step-by-step explanation:

Particles in both liquids and gases (collectively called fluids) move randomly. This is called Brownian motion. They do this because they are bombarded by the other moving particles in the fluid. Larger particles can be moved by light, fast-moving molecules.

Answer 2

Answer:

Brownian motion, or pedesis is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving molecules in the fluid.
