2.  Matter is anything that has mass and takes up space. What is matter?

3. 1. All matter is made up of extremely small particles

4. 2. All particles of one substance are the same. Different substances are made of different particles.

5. 3. There are spaces between the particles.

6. 4. The particles are always moving. The more energy that particles have, the faster they move.

7. There are attractive forces among particles. These forces are stronger when the particles are closer together. 5. There are attractive forces among particles. These forces are stronger when the particles are closer together. particles far apart – force weak particles close together – force strong

8.  SOLID  LIQUID  GAS

9.  Strong attraction  Particles only vibrate

10.  Weaker attraction  Particles move past each other

11.  Attraction very weak  Particles far apart

13. MATTER mixture pure substances compoundselementssolutions(homogenous mechanical mixture (heterogenous)

14. MATTER anything that has mass and takes up space (eg. desk, ppl) Mixture contains 2 or more substances (eg. pizza, fruit punch) Pure substances all “particles that make up the substance are the same (eg. water) Compounds contain 2 or more elements in a fixed proportion (eg. H 2 O, CO 2 ) Elements cannot be broken down into simpler substances (eg. carbon, oxygen) Homogenous mixture (solution) contains one visible component (eg. tea, vinegar, fruit punch) Heterogenous (mechanical) mixture Contains more than one visible component (eg. Italian salad dressing, raisin bran)
