The uk gas market became a public discussion point in the period from 1967 to 1977 during the switchover from town gas, made from coal, to natural gas, following the discovery of natural gas in the uk sector. Ideal gases experiment shows that 1 mole of any gas, such as helium, air, hydrogen, etc at the same volume and temperature has almost the same pressure. Natural gas is a combustible, gaseous mixture of simple hydrocarbon compounds, usually found in deep underground reservoirs formed by porous rock. Using this factor, the ideal gas equation becomes a real gas equation.

An ideal gas is one that conforms exactly to the tenets of the kinetic molecular theory, where the volume occupied by the gas particles is negligible relative to the total volume of the container, and there are no appreciable intermolecular attractions or repulsions real gases can deviate from ideal behaviour, especially at high pressures and low temperatures. Under ideal conditions, this ratio of pvrt should be exactly equal to 1. Where p is the pressure, t is the temperature, r the ideal gas constant, and v m the molar volume. Real gases show deviations from the perfect gas law because molecules interact with one. The gas then is allowed to expand into another insulated chamber with volume v 2.
