What is the Ideal Gas Law?
The Ideal Gas Law (PV = nRT) describes the relationship between pressure (P), volume (V), number of moles (n), and temperature (T) for an ideal gas. R is the gas constant.
Assumptions of Ideal Gas Law
The ideal gas law assumes:
- Gas particles have negligible volume
- No intermolecular forces
- Perfectly elastic collisions
- Random motion of particles
- Constant random motion
Real vs. Ideal Gases
Deviations from ideal behavior occur due to:
- High pressures
- Low temperatures
- Strong intermolecular forces
- Large molecular size
Applications
The Ideal Gas Law is used in:
- Chemical reaction calculations
- Industrial process design
- Weather prediction
- Respiratory physiology
- Hot air balloon design
