Gas Laws, Part 2 Charles’ Law Lab Demonstration
REVIEW:The Law of Conservation of Mass “For any normal, chemical reaction, matter is neither created nor destroyed.” C2H6+ O2CO2 + H2O
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.
Lab Demonstration: Charles’ Law Materials: Soda Can Tongs Ice Water Plastic Tub Heat Source Tap Water
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
