You can get the concept of: Thermal coefficient of tension, general equation of state of ideal gases, universal gas constant, Law Amontons'.
Principle: State of the gas determined by its temperature, pressure and quantity of the substance. For the case of an ideal gas, these state variables are related by the general equation. For the particular case under isochoric conditions, this equation becomes law Amontsona. In the experiment, checking the conformity of theoretical and experimental data, the example of air.
