Question

The volume occupied by the molecules of an ideal gas is :

Answer 1

An ideal gas is defined to be a system in which there are no intermolecular/interatomic forces. Such a system can only exist as a gas. Any real system will approach ideal gas behaviour in the limit that the pressure is extremely low and the temperature is high enough to overcome attractive intermolecular forces. An ideal gas is a gas to go which the laws of Boyle and Charles are strictly applicable under all conditions of temperatures and pressures and volume occupied by the molecules of an ideal gas is zero.
