Brownian Motion
the random movement of microscopic particles suspended in a gas or liquid
What causes Brownian Motion?
collision of small molecules in the surrounding medium
Absolute zero
-459 degrees F
What causes the molecules to move or vibrate?
kinetic energy of all molecules above absolute zero
The rate of molecular moment depends on what three things?
1. amount of energy (Heat) (More energy= more movement)
2. size (smaller the faster the movement)
3. state of matter (gas molecules=faster)
