Observe how particles move
Atoms and molecules are constantly vibrating and in gasses and liquids they are constantly moving around. Watch how a drop of food colouring diffuses (moves) through a glass of water. Click anywhere in the model container to add a drop of dye to the water. Use the "Trace Random Molecule" button to follow a single molecule.

Check how temperature and molecular mass affect diffusion.
Change the molecular mass or the temperature then remove the barrier to let the pink molecules diffuse through the green molecules. When three pink molecules reach the gas sensor, the experiment will stop. Compare the time it takes for the pink molecules to diffuse at different temperatures and at different weights.

Basic outline, excellent stuff but a lot less detail and not interactive - superb for a quick overview or last minute revision

Exam Style Question
write on paper first
editable version
The form below can only be used once since it provides the correct answers and examiners marking feedback once submitted. Your entry cannot be edited and the form will not save and continue, don't use until you are ready to give a complete answer .
If you're short of time then use the version opposite. This does not provide correct answers or examiners feedback but it CAN be edited after you have submitted - you can then copy and paste into the form below when you are ready with a full answer.
