    • Read Chapter 14 - sections 1, 2 and 3 and develop chapter notes as class assignment - 50 points
  • HOW
    • Use the Cornell style of note taking
    • Divide paper as shown in class or on the handout
    • On the left side of the fold, write the facts from the reading
    • On the right side of the fold, write how you think this will help you, why the fact is important or interesting, or a question about that fact.
    • There should be as much on the right side of the page as there is on the left of the page.
    • Details go on the right, simple statements on the left.
    • Start each section on a new page. Use labels such as "kinetic theory" or ‘Avogadro’s Prinicple" as headings for the pages or the left hand column.
    • Look at the summary on page 447 for hints on main ideas for left column – right column should be explaination and detail.

The Lab Problem
 

Unit 10 Gas Laws Lab - Introduction and Instructions - Lab worth 100 points

Your task:

Apply the experimental procedure of water displacement in order to obtain data necessary to determine the identity of the propellant in canned air using gas law relationships.

Step 1 - Ask yourself questions, then seek answers:

You Should Seek Answers to these questions in order to begin
  1. What is water displacement?
  2. What is water vapor and how will it influence my data?
  3. What is STP and how will it influence my data?
  4. What are the variables in this experiment?
  5. Which variables can I control and how?
  6. Where will I find information about gases and gas laws? The Answers... see the text assignment above.
  7. What propellents are possible? The Answer...
    Propane C3H8
    Butane C4H10
    Dichlorodifluoromethande, CCl2F2
    Difluoroethanne, C2H4F2
  8. What materials are available to use in lab testing? The Answer...

Can of compressed gas
Mass scale
Tubing
3 liter bottle marked at 2.24 L
plastic bin for water
tubing and tape for connections
ice
thermometer
barometer

Step 2 - Plan a Procedure:

Using what you have learned about gas laws and from discussions on using water displacement to find volume, plan a procedure to let you determine the identity of the propellent. Include an organized table to record data.

Step 3 - Perform Your Procedure

Step 4- Perform Needed Calculations from Experimental Data

Step 5- Take A Quiz

Step 6- Write Lab Report
