What to Focus On
- Matter is made up of extremely small particles.
- A constituent particle is the basic unit of a substance.
- Grinding chalk is a physical change, not a chemical change.
- Interparticle spaces exist between particles of matter.
- Dissolved sugar occupies spaces between water particles.
- The volume of a sugar solution is less than the sum of separate volumes.
- Interparticle attractions hold particles together.
- Their strength depends on substance and distance.
- Attraction is strongest in solids, weaker in liquids, and weakest in gases.
Common Mistakes to Avoid
Particles in solids are packed tightly, but the spaces between them are filled with air.
Sugar disappears in water because it gets destroyed or vanishes.
If a solid dissolves in water, the total volume must always increase because one substance has been added.
Memory Tips
