|---|---|
| Definition of diffusion | It is the net movement of particles from a region of higher concentration to a region of lower concentration as result of their random movement. |
| State how the particles of a solid, liquid and gas are arranged. | Solid- Particles are in a fixed pattern(lattice) due to strong forces of attraction so they cannot leave their positions but are able to vibrate. Liquid- Particles can move about and slide past each other, the particles are clos to each other but not in a lattice as the forces holding them are weaker than in a solid. Gas- Particles are far apart and move about very quickly since there's almost no force holding them together. |
| What are the two ways to increase gas pressure? | Decreasing the volume of container increasing the temperature |
| What are the two factors that affect the rate of diffusion | Mass of particles Temperature |
