Correct Answer: low pressure and high temperature

Solution : The correct option is low pressure and high temperature.

Under the following conditions, a real gas can serve as an ideal gas: Low pressure: When a gas's pressure is low, its molecules are widely apart and have minimal contact with one another. This indicates that the gas can behave like an ideal gas, in which the molecules have no volume and do not interact with one another. High temperature: When a gas's temperature is high, its molecules have a lot of kinetic energy. This suggests they are travelling very quickly and are unlikely to interact with one another. This also implies that the gas has the potential to act like an ideal gas.
