1 Bell Ringer Get out “States of Matter” flow chart from yesterday

2 States of Matter & Changes of State

3 Molecules Solid Has a definite shape and volume
Molecules are packed tightly together Molecules only vibrate slightly Molecules are VERY attracted to each other Molecules

4 Molecules in a glass of water
Liquid Has a definite volume but no definite shape (Takes the shape of its container) Molecules are packed almost as tightly as a solid Molecules move freely around each other Molecules are somewhat attracted to each other. Molecules in a glass of water

5 Gas Molecules in a sealed container
No definite shape or volume As gas molecules spread apart, they fill all the available space. (takes on shape of container) Molecules move at high speeds in all directions Molecules not attracted to each other. Gas Molecules in a sealed container

6 Plasma Molecules in a sealed container
No definite shape or volume As plasma molecules spread apart, they fill all the available space. (takes on shape of container) plasma is made by heating a gas until its electrons have enough energy to escape the hold of the nucleus. Plasma Molecules in a sealed container e- e- e-

7 Changes of States

8 Solid Solid to Liquid Melting Solid to Gas Sublimation

9 Liquid Liquid to Solid Freezing Liquid to Gas
Evaporation– happens at surface Boiling– happens below surface

10 Gas Gas to Solid Deposition Gas to Liquid Condensation

11 Quiz After quiz: Finish reading from yesterday, if needed, blue book page 18-22
