What Are 4 Examples of Real Gases and Their Characteristics?
Explore 4 common real gases like oxygen and carbon dioxide, and understand how real gases deviate from the Ideal Gas Law.

Real gases are those that do not perfectly follow the Ideal Gas Law under many conditions. Examples include oxygen (O2), nitrogen (N2), carbon dioxide (CO2), and helium (He). These gases demonstrate real behavior due to their intermolecular forces and the volume occupied by the gas molecules themselves, especially under high pressure and low temperature conditions.
FAQs & Answers
- What distinguishes real gases from ideal gases? Real gases differ from ideal gases because they take into account intermolecular forces and the actual volume of gas molecules, which causes deviations from the Ideal Gas Law especially at high pressure and low temperature.
- Why do gases like oxygen and carbon dioxide behave as real gases? Oxygen and carbon dioxide behave as real gases because their molecules exert intermolecular forces and occupy finite volume, affecting their behavior under non-ideal conditions such as high pressure or low temperature.
- Under what conditions do gases behave most like real gases? Gases exhibit real behavior primarily under high pressure and low temperature, where molecular interactions and volume have significant effects unlike what the Ideal Gas Law assumes.
