P4 SIMPLE KINETIC AND MOLECULAR MODEL OF MATTER
Before you start you can look back at 7G Solids, Liquids and Gases
If you only remember one thing:
PRESSURE IN GASES IS CAUSED BY THE FORCE OF PARTICLES HITTING THE WALLS OF A CONTAINER.
This is the fourth of the 15 Physics units:
P2. Matter and Forces
P3. Energy, Work and Power
P4. Simple Kinetic Molecular Model of Matter
P5. Matter and Thermal Properties
P6. Transfer of Thermal Energy
P9. Electromagnetic Spectrum
P13. Electric Circuits
P14. Electromagnetic Effects
LESSON 1: STATES OF MATTER AND GAS PRESSURE
There are 2 videos in this lesson. You have to watch them both.
A nice little animation explaining the states of matter from the ABPI.
There are many other states of matter in real life. Here is a nice video explaining Plasma (the fourth state of matter)
Try the PhET simulation yourself.
