How can I do Charles' law experiment?

Question

Caleb Adams · Accepted Answer

Got a large piston?

You could actually make a large piston with a plastic disposable syringe of approx. #50-100# #mL# volume. Draw in air to full volume at room temperature, i.e. #50# #mL#, seal the tip, and drop the syringe in an ice water bath. Is #V# #prop# #T#? Of course you need several constant temperature water baths at (say) #0^@, 10^@, 20^@, 30^@, 40^@, 50^@# #C#, to get meaningful results.

undefined To perform an experiment based on Charles' law, you will need the following materials:

1. A gas-filled syringe or a container with a gas sample
2. A thermometer
3. A water bath or heat source (e.g., hot plate or Bunsen burner)
4. A ruler or measuring tape
5. Safety goggles and gloves (for handling equipment and potential hazards)

Procedure:
1. Start by measuring the initial volume (V1) of the gas sample using the syringe or container.
2. Measure the initial temperature (T1) of the gas sample using the thermometer.
3. Place the gas sample in the water bath or heat source to change its temperature.
4. After the temperature change, measure the final volume (V2) of the gas sample.
5. Measure the final temperature (T2) of the gas sample.
6. Calculate the ratio of the initial volume to the initial temperature (V1/T1).
7. Calculate the ratio of the final volume to the final temperature (V2/T2).
8. Compare the ratios obtained in steps 6 and 7 to verify if they are approximately equal, as predicted by Charles' law.

Remember to record all measurements accurately, and repeat the experiment multiple times to ensure reliability. Additionally, follow proper safety protocols when handling equipment and heat sources to prevent accidents or injuries.
