Work with one partner and find the following information by visiting the websites or using the books.

Gas Laws

Chemistry Laboratory – Internet – Web- Book Inquiry in the Library.

Gases have the following physical properties:

1. No set shape or volume
2. Expand to fill the shape of the container
3. Can be compressed by increasing pressure
4. Mix completely and spontaneously
5. Move constantly, quickly and randomly (Like Mrs. Flower, eh?)
6. No strong molecular forces between particles
7. When particles collide no energy is lost
8. All collisions are elastic
9. Low density

At STP: 1 ATM = 760 mmHg = 101.3 kPa @  _________ K (temperature)

Look up the temperature on the reference table.

Three famous scientists studied gases and hence gas laws are named after them. Please see your librarian for books about Famous scientists and write one paragraph about each of the three scientists and the gas law and experiment they did:

One website is: http://www.chem.uidaho.edu/~honors/gas.html

Use Microsoft Encarta, Encyclopedias, etc

Mr. Avogadro – an Italian Physicist in 1811

Now that we know a little about these famous scientists who were concerned with GAS, lets play with some simulation on the Web.

Remember Kinetic Theory and the characteristics of gases described above?

Open this site and investigate what happens when you use 5, 20 and 50 particles:

http://comp.uark.edu/~jgeabana/mol_dyn/KinThI.html

Type in the address and spend time changing the values of particles (#), pressure and velocity.

Write down what you see – draw a picture and observe – tell me what is going on.

Now let’s look at temperature and gases:

Write down what you see – draw a picture and observe – tell me what is going on.

Expert Knowledge for those who are interested…

Using Gas:

Think about how you use and sometimes make in your life.

Brainstorm with your partner and name 3 other things you may use gas for.  Go to the web or librarian and find one thing uses or is gas.  Find one website that has information about the gas. Print the site and attach it to your lab report.
