A sample of a real gas acts more like an ideal gas when the volume is increased at constant temperature. Why does this happen?
1) The molecules are farther apart, so the attractive or the repulsive are less of a factor.
2) Collisions between molecules are less forceful after the decrease in pressure.
3) The volumes of the molecules become less significant compared to the volume of the container.
