1. States of Matter Solid Liquid Gas Plasma

2. Objective You will be able to characterize and differentiate between the different states of matter.

3. Your turn… Write three (3) examples EACH for -Solids -Liquids -Gases **Try to use examples you have personally been in contact with

4. How they relate Based on what you know about solids, liquids, and gases, how are the 9 examples you came up with different and how are they similar? Write it down!

5. The Three States of Matter We Will Consider… Solids – Solids – Orderly arrangement of particles that compose it: atoms, molecules, or ions Orderly arrangement of particles that compose it: atoms, molecules, or ions Held together by forces that keep them in fixed positions Held together by forces that keep them in fixed positions Does not flow; difficult to compress Does not flow; difficult to compress

6. The Three States of Matter We Will Consider… Solids – Volume and shape are constant because of fixed position Volume and shape are constant because of fixed position When heated, particles gain energy and the solid becomes a liquid When heated, particles gain energy and the solid becomes a liquid Identified by an (s) in chemical equations Identified by an (s) in chemical equations Fe 2 O 3 (s) + Al (s)  Fe (s) + Al 2 O 3 (s)

7. The Three States of Matter We Will Consider… Liquid – Particles are farther apart than those of a solid, but still fairly close to one another Particles are farther apart than those of a solid, but still fairly close to one another Liquids flow because of greater distances between particles Liquids flow because of greater distances between particles Difficult to compress because the particles remain in contact even as they move about Difficult to compress because the particles remain in contact even as they move about

8. The Three States of Matter We Will Consider… Liquid – Volume is constant, but liquids can flow to change shape into that of its container Volume is constant, but liquids can flow to change shape into that of its container Cooled = solid; heated = gas Cooled = solid; heated = gas Identified by a (l) in a chemical equations Identified by a (l) in a chemical equations H 2 O (s)  H 2 O (l)

9. The Three States of Matter We Will Consider… Gas – Very large distances between particles that are moving at high speeds – 300 m/s Very large distances between particles that are moving at high speeds – 300 m/s Can be compressed because of large spaces between particles Can be compressed because of large spaces between particles

10. The Three States of Matter We Will Consider… Gas – Gases flow because particles are in constant motion Gases flow because particles are in constant motion Always fill the volume and Always fill the volume and shape of the container in which they are placed Identified by a (g) in a chemical equations Identified by a (g) in a chemical equations 2 HCl (aq)+ Zn (s)  ZnCl 2 (aq) + H 2 (g)
