Question

Real gases behave ideally at:

• A. Low pressure, high temperature
• B. Low pressure, low temperature
• C. High pressure, low temperature
• D. None of these

Answer 1

The correct option is A Low pressure, high temperature

Real gases behave ideally at low pressure and high temperature. Under these conditions, the gas molecules are sufficiently apart so that the intermolecular forces of attraction are negligible and the volume occupied by the gas molecules is negligible in comparison to the total volume of gas. These conditions favour ideal gas behaviour.

Hence, the correct option is $\text{A}$
