  1. Bell Work Get out a blank piece of paper for notes. Put this heading: Your Name and Period # Notes 2-6: Exploring Charles’ Law Homework Tonight: Read page 222-227 in “Science Interactions” text.

  2. Gas Laws, Part 2 Charles’ Law Lab Demonstration

  3. REVIEW:The Law of Conservation of Mass “For any normal, chemical reaction, matter is neither created nor destroyed.” C2H6+ O2CO2 + H2O

  4. Review: Charles’ Law: For a fixed amount of gas a constant pressure, volume and temperature are directly proportional In other words, when the temperature of a gas increases, its volume also increases. The same is true in reverse: When the temperature of a gas decreases, its volume decreases.

  5. Lab Demonstration: Charles’ Law Materials: Soda Can Tongs Ice Water Plastic Tub Heat Source Tap Water

  6. Lab Demonstration: Charles’ Law Procedure: Place a few drops of water into an empty soda can. Place can on a heat source (electric burner) until water vapor is visibly exiting through the top Quickly remover the can from the burner, using the tongs Place the can upside down in the ice water Record observations

  7. Lab Demonstration: Charles’ Law What do you think will happen? Write down your PREDICTION:

  8. What happened? Write down your OBSERVATIONS:

  9. Lab Demonstration: Charles’ Law How can your explain what your saw? Write down your Explanation of Results & Conclusion:

  10. Charles’ Law: Yes, this really happened…

  11. Charles’ Law: Review & Conclude: Charles’ Law states that, when a fixed amount of gas, at a fixed pressure INCREASES in TEMPERATURE its VOLUME will…? Charles’ Law states that, when a fixed amount of gas, at a fixed pressure DECREASES in TEMPERATURE, its VOLUME will…?
