Experiment: Boyle's Law and the Advancement of Modern Chemistry


Objective: To demonstrate the inverse relationship between the pressure and volume of a gas at constant temperature, as described by Boyle's Law.
Materials:
  • Two glass syringes (with plungers removed)
  • A balloon
  • A stopcock
  • A graduated cylinder
  • Water
  • A ruler
Procedure:
  1. Attach the balloon to one end of the stopcock and the syringe to the other end.
  2. Fill the syringe with water to a known volume (e.g., 10 mL).
  3. Close the stopcock and push the plunger of the syringe to increase the pressure inside the balloon (Note: The original instructions said "pull", which is incorrect for increasing pressure).
  4. Observe the balloon as the pressure increases. Record the volume of the balloon at regular intervals. You may need to estimate the volume of the balloon.
  5. Once the balloon is fully inflated, slowly open the stopcock to release the air.
  6. Observe the balloon as the pressure decreases. Record the volume of the balloon at regular intervals. You may need to estimate the volume of the balloon.
Key Considerations:
  • Ensure that the temperature of the gas remains constant throughout the experiment.
  • Apply pressure to the gas slowly and steadily to ensure accurate measurements.
  • Record the pressure and volume of the gas accurately at each data point. A pressure gauge could be incorporated for more accurate results. Measuring the volume of the balloon directly is difficult. An alternative would be to measure the volume of air in the syringe, understanding that the volume of the air in the balloon is the total volume (syringe + balloon) minus the volume of water in the syringe.
Significance:
  • This experiment demonstrates Boyle's Law, which is a fundamental principle of gas behavior.
  • Boyle's Law has numerous applications in chemistry, including the design of gas storage systems, the study of gases in chemical reactions, and the development of other gas laws.
  • This experiment also highlights the importance of experimental observation and data analysis in advancing scientific understanding.
Conclusion:
The results of this experiment, when properly conducted and analyzed, should support Boyle's Law, demonstrating the inverse relationship between the pressure and volume of a gas at constant temperature. This experiment contributes to the advancement of modern chemistry by providing a foundation for understanding gas behavior and its applications in various fields. Note that using a balloon makes precise measurements challenging; better equipment would produce more conclusive results.
