If the gas contained in a vessel at a constant temperature and pressure (reservoir) is left to expand in the vacuum through a sonic nozzle, a supersonic jet is generated. A relevant part of thermal energy, initially existing in the stagnating gas, is converted to kinetic energy of the directional mass flow, and the various degrees of freedom of the molecules are cooled to different extents.
