An ideal gas is a perfect gas. There is no ideal gas in the world. An ideal gas would follow the combined gas law exactly in any environment. A gas whose pressure P, volume V, and temperature T are related by PV = nRT, where n is the number of moles of gas and R is the ideal gas law constant. Ideal gases have molecules with negligible size, and the average molar kinetic energy of an ideal gas depends only on its temperature.
