1. Do now: In your notes, draw a picture, WITH A TITLE ABOVE IT, that shows gas molecules applying pressure to the walls of a container (use arrows to indicate movement of gas particles).
2. Go to: http://www.shodor.org/unchem/advanced/gas/
Title next section : 2. Why Gases are Unique? Provide three reasons below:
a)
b)
c)
3. Title this section:
3. Factors that affect the behavior of Gases:
Write the letters below, each in a different color. Define each quantitative descriptive variable of gases. Then write down ALL of the possible units that each variable can measured in. Use your reference table.
P
V
T
n
4. Title this section:
4.Avogradro's Hypothesis
in this section, write the standard molar volume of All Ideal Gases. Then explain what this number means.
in this section, write the standard molar volume of All Ideal Gases. Then explain what this number means.
Title: 5. Ideal vs. Real Gases
Answer the following questions in order, underneath the above title.
1.Write equation for IDEAL GASES, and explain its purpose.
then, go to: http://preparatorychemistry.com/Bishop_Real_Gases.htm
2. What happens to gas molecules that get close together at very high temperatures? decreasing T?
3. describe the properties of an ideal gas
4. Under what conditions is the ideal gas law NOT applicable? Why do you think at these conditions, do gases behave differently?
5.Draw 2 pictures: A) use arrows to indicate the movement of molecules in an ideal gas. B)use arrows to indicate how real gases are different.
6. title: 6. Collision Theory:
Which type of gas, real or ideal, do you think involves significant collisions between gas particles? How do you know?
7. title: 7. STP
1. Do a web search for STP gases. Then describe what the S.T.P. each stand for
2. What are the values of T and P at STP?
3. What is the standard volume of ANY diatomic (O2, N2, CL2 etc...) gas at STP?
