Description In school practice we always determine the density of solids and liquids, but measuring the density of gas is silently ignored. This is caused by absolute value of the density of the gas, which can not be neglected lift force, first, the volume dependence and in particular the pressure in the equation of state. For gases, the density can vary over a wide range because the particles are free to move closer together when constrained by pressure or volume. To measure the gas density, we used several methods of measurement using a vacuum. These experimental tasks are suitable for groups of talented students, because they require a greater degree of imagination.
