2-1 States of Matter
Review the states of matter and find out a few details that we didn't discuss previously by answering the questions listed with each state of matter.
Solids: (previously we learned that the molecules are closely packed and that solids cannot change their shape or volume)
** What is the difference between crystaline and amorphous solids?
** Give an example of a crystaline substance.
** Give an example of an amorphous substance.
Liquids: (previously we learned that the molecules are spread out far enough to flow past each other and that liquids cannot change their volume but change shapes to match the shape of their containers)
** Explain viscosity.
** Give an example of something with a high viscosity.
** Give an example of something with a low viscosity.
Gases: (previously we learned that gas molecules are very far apart; gases take on the volume and shape of their containers) - No questions at this point on gases, the rest of the chapter is on gas laws!
Plasma: ( previously we learned that gases at extremely high temperatures become plasma)
** What is plasma?
** How does plasma form?
Bose-Einstein Condensate (BEC)

2-3 Graphing Gas Laws
1) Read pages 56 - 59 on graphing gas laws. Write a 1 sentence summary for each green and purple heading. Then do page 59 #1-4. Put this all in a google doc and share with me at Brooksj@jenkintown.org
2) Then do the questions in the following internet activity
