Key Concepts: Real Gases & Deviations

Core Definitions

• Real Gases: Actual gases that deviate from ideal behavior, especially at high pressure and low temperature.
• Intermolecular Forces: Real gas particles DO attract each other, unlike ideal gas assumptions.
• Particle Volume: Real gas particles DO occupy space, unlike the ideal assumption of negligible volume.
• High Pressure: Particles are forced close together; volume and intermolecular forces become significant.
• Low Temperature: Particles move slowly; attractive forces have greater effect, causing deviation.
• Most Ideal Behavior: Gases behave most ideally at HIGH temperature and LOW pressure.
