Question

Under which of the following conditions do you think a real gas behaves as an ideal

• A. High pressure
• B. Intermediate pressure
• C. Low pressury
• D. At any pressure

Answer 1

Answer:

C. Low pressury

• A real gas behaves as an ideal gas under conditions of low pressure and high temperature.

• At low pressure: The molecules of the gas are spread very far apart from one another.

• Because of this large separation, the actual volume of the gas molecules becomes negligible compared to the total volume of the container, and intermolecular forces of attraction become virtually zero
