It is inconvenient to define, who the first has entered gas constant R. Possibly, the idea is so obvious that nobody aspired to declare a priority. All textbooks enter R by the way as the necessary consequence from laws of Bojlja and Charles is indeed actually.

Gas laws make the beginning of a subject of the thermodynamics representing considerable practical and theoretical interest.

So, as a result of several simple experiments such picture of behaviour of gases about which the first researchers and did not assume has come to light. For them various gases represented ' vozdu-hi ' which, obviously, should be so various on the properties, as liquids or firm bodies. The laws found them, have made a basis for the kinetic theory of gases according to which gases consist of incalculable set of the smallest molecules rushing back and forth and incessantly striking in walls of a vessel. The law of Avogadro says that at the given temperature and pressure equal volumes of gases contain identical numbers of molecules, and from it definition of the important physical constant - numbers of Avogadro, number of molecules in a gramme-molecule follows.
