The correct Answer is:
To determine the conditions under which a real gas behaves like an ideal gas, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Real vs. Ideal Gas**: - An ideal gas is a hypothetical gas that perfectly follows the gas laws without any exceptions. Real gases, however, have interactions between molecules and occupy space, which can cause deviations from ideal behavior. 2. **Identify Conditions for Ideal Behavior**: - Real gases behave like ideal gases under certain conditions. These conditions are primarily related to temperature and pressure. 3. **Average Distance Between Gas Molecules**: - For a real gas to behave like an ideal gas, the average distance between gas molecules must be large enough. This occurs when the gas is at low pressure, which allows the molecules to be far apart. 4. **Force of Attraction**: - When the average distance between gas molecules is large, the forces of attraction between them become negligible. This means that the intermolecular forces can be considered almost zero. 5. **Volume Considerations**: - The actual volume occupied by the gas molecules becomes negligible compared to the volume of the container. This means that the volume occupied by the gas molecules does not significantly affect the overall behavior of the gas. 6. **Pressure and Temperature Relationship**: - The conditions under which these effects are observed (negligible forces of attraction and negligible volume) are typically at low pressure and high temperature. Under these conditions, the gas molecules are moving rapidly and are far apart, minimizing interactions. 7. **Conclusion**: - Therefore, a real gas behaves like an ideal gas when the pressure is low and the temperature is high. ### Final Answer: A real gas behaves like an ideal gas if its pressure is low and temperature is high. ---
