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?

 **  What are some properties or uses of plasma



 Bose-Einstein Condensate (BEC)

Go to the BEC Homepage (www.colorado.edu/physics/2000/bec/)

NIST website on the BEC

Answer the following questions:

  1. Who first predicted the existence of the BEC and in what year?
  2. Who actually first created the BEC in 1995?
  3. Where is the coldest place in nature and how close to absolute zero is it?
  4. What temperature did the BEC form at?
  5. How did Bose and Einstein come up with the idea of the BEC?
  6. In 1995, how did they actually create the BEC?
  7. Why don’t they know yet what the BEC could be used for?
  8. Write a few sentences on something you found interesting on the BEC.

2-2  Gas Laws,

Part 1:  What variables affect gases: 

Use the resources below to answer the following


  1. What are three measurements needed to discuss gases? 
  2. How do you measure them? 
  3. What do they measure? 
  4. What are their units?

Part 2:  The gas laws that relate the variables above

Use the resources below to investigate the gas laws.  Write 3 paragraphs summarizing the gas laws.  One should summarize Boyle's Law, one on Charles' Law, and one on the relationship between Temperature and Pressure (No Name Law).  Also include an example from real life that shows each of the 3 gas laws.

2-3  Graphing Gas Laws

 Notes on 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
