The video tutorial demonstrates an experiment using a balloon to illustrate Charles' Law, which relates gas volume and temperature. The experiment involves three trials: at room temperature, in a freezer, and in a hot water bath. Measurements of the balloon's circumference are taken to calculate volume changes. The results are analyzed using the combined gas law, confirming the relationship between temperature and volume. The experiment also calculates the unknown temperature of the hot water bath using the gas law.
