An Ideal Gas is a theoretical gas that is defined as all collisions between atoms or molecules are perfectly elastic, molecules occupy negligible space and no intermolecular attractive forces. The Ideal Gas follows the ideal gas law, which is the relationship described by the equation PV = nRT where, P is pressure, V is volume, n is the number of moles of an ideal gas, R is the ideal gas constant (0.082057), and T is the temperature. One mole of an ideal gas has a volume of 22.4 litres at the standard temperature and pressure (STP).
