Abstract. Three experiments are described. They illustrate the ideal gas law and cover the determination of molecular weight, the dependence of volume on the number of moles, and pressure as a function of the number of moles. A disposable lighter is used as the gas source. The experiments are suggested for use as regular laboratory exercises or as lecture demonstrations.
