1 8/24

2  Matter - any substance which has mass and takes up space  List 5 Examples of Matter:  List 5 Examples of things that are NOT matter:

3  When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase.

4  These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.

5  Solid – form of matter with a definite shape and volume, individual particles vibrate but do not switch positions. (Least amount of energy and movement)

6  Liquid – particles are attracted to each other, but are not in a fixed position.  (A little more energy and movement)

7  Gas – particles have enough energy to overcome any attractions. Particles move freely and independently.  (Even more energy and movement)

8  Plasma – high temperatures cause some of the electrons normally found in an atom to escape and move outside of the electron cloud.  Found in stars, the sun, the solar wind, lightning, fire and neon signs.  (The most energy and movement)
