Real Gases: Deviations from the Ideal Gas Law

• Under non-ideal conditions, real gas particles

– do have volume.

• Meaning, the volume of a gas is
• Volume of gas particles + volume of the flask
• have intermolecular forces.
• Otherwise, a gas could not become a liquid
• Also, this implies that there are attractions between gas particles.
• Collisions are therefore not elastic in nature.

– Pressure of a gas is not just due to the gas particles colliding with the container walls.
