अधिकांश गैसें आदर्श व्यवहार से विचलित होती हैं:
Explanation
Real gases deviate most from ideal behavior under conditions where:
Low temperature:
- Molecules move slowly
- Intermolecular forces become significant
- Attractive forces cause Z < 1
High pressure:
- Molecules are forced close together
- Molecular volume becomes significant
- Repulsive forces cause Z > 1
- Both attractive and repulsive effects are amplified
Ideal conditions:
- High temperature: Molecules move fast, overcome attractions
- Low pressure: Large intermolecular distances, negligible interactions
Real gas effects:
- van der Waals forces (attraction)
- Finite molecular size (repulsion)
- Both effects are minimized at high T, low P
