A gas is said to behave like an ideal gas when the relation PV/T = constant. When do you expect a real gas to behave like an ideal gas?

1. When the temperature is low
2. When both the temperature and pressure are high
3. When the temperature and pressure are high
4. When the temperature is high and pressure is low

Correct answer: When the temperature is high and pressure is low

Solution

Real gases behave like ideal gases at high temperature and low pressure because intermolecular forces become negligible and the gas molecules occupy negligible volume compared to the container.
