प्रश्न
Explain whether a gas approaches ideal behavior or deviates from ideal behaviour if more gas is introduced into the same volume and at the same temperature.

उत्तर
When more gas is introduced into a container of the same volume and at the same temperature, the compressibility factor tends to unity. Hence, the gas behaves ideally.
