Procedure

  1. Put on your safety glasses and gloves (provided in your safety box).
  2. Stretch the opening of the balloon around the opening of the Erlenmeyer flask. Use the ruler to confirm the neck of the balloon reaches at least one centimeter down the neck of the flask. Use your camera (or smart phone) to take a picture of the flask with balloon attached.
  3. Place the Erlenmeyer flask inside of a pot.
  4. Fill the pot with water until it reaches the 100 mL mark on the flask.
  5. Put the pot on a stovetop burner and set the heat to low (no higher than 3 on a standard stovetop). The water should be visibly heated with small bubbles forming at the bottom, but should not be boiling.
    LAB SAFETY: Use caution when working with glassware and heat. Never touch the glassware without a hot pad and always protect your eyes with safety glasses. Monitor the apparatus at all times.
  6. Observe the system and record your observations after 10 minutes in Post-Lab Question 1.
  7. Turn off the stovetop and use the hot pad to carefully remove the flask and balloon system from the pot.
  8. Use your camera (or smart phone) to take a picture of the heated flask and balloon. Be sure to correctly label the picture and send it to your instructor, along with the answers to the post-lab questions.  
  9. Let the flask rest on a heat resistant counter top or hot pad for 10 minutes. Record your final observations in Post-Lab Question 1.

Use your camera or smart phone to take a picture of the cooled flask and balloon. Be sure to correctly label the picture and send it to your instructor, along with the answers to the post-lab questions.
