Easy to modify to fit your needs! Ideal Gas Law. The ideal gas law is an important part of chemistry, but students often get bogged down with the mathematical part and miss the big picture. Use the Gas Thermometry technique to validate the Ideal Gas Law. The ideal gas law is also known as the general gas equation. Can you think of any ways to reduce the error, perhaps with more time or with additional resources? Not exactly an experiment, but if you simply take a balloon and blow it up it can be represented by the ideal gas law since you are increasing the pressure and volume you must also be adding more molecules of air from your lungs. It demonstrates a direct relationship between the two variables (ex: as one goes up, the other goes up). Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. Experiment 1. The law was first stated by Émile Clapeyron in 1834.
