<prompt> Characteristic of an ideal gas isVolume is directly proportional to change in pressureVolume is inversely proportional to change in temperatureAt absolute temp. volume of gas is 1Obeys Charles, Byles and Avagadro laws  <response>: An ideal gas is one which obeys Boyles law, charles law and Avogadro law :-The ideal gas equation is :-Volume v number of moles n × gas constant R × Temperature T Pressure P Byoles law :-At a constant temperature, volume of gas is inversely proportional to pressure see ideal gas equation.Charles law :- At a constant pressure, volume of gas is direct proportional to temperature see ideal gas equation.Avogardos low :- Equal volumes of gas at same temperature pressure contains same number of moleules.At standard temperature the volume of a mole of gas is 22.4 liters.
