The hypothesis is that helium at 60°C or lower will have more volume than any of the other gases at the same temperature or lower.

You will fill 10 Mylar balloons with different gases, attach them to a bucket, and submerge them in water at different temperatures. You will measure the volume of each gas and record the data.

You will need a bucket, fishing line, a graduated cylinder, a beaker, a thermometer, 10 Mylar balloons, a cap, an S-hook, silicone, a pipe, eye bolts, and a piece of tubing.

The results indicate that as the temperature of any gas was increased, the volume would also increase. Oxygen had an overall percentage volume change of 36.5%, nitrogen changed 21.8%, argon had a 20.5% change, helium had a 16.4% change, and carbon dioxide changed 15.3%.

This science project is interesting because it shows how different gases expand when heated, which can be useful for understanding how to use different gases in balloons.

Experiment variations to consider include using a different size balloon and adding something to the water like salt.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
