Ideal Gas:
• A gas whose volume varies in proportion to temperature and in inverse proportion to pressure.
• Noble gases such as helium and neon approach ideal behavior because of their low intermolecular forces.

Ideal Gas Laws:
• Gas molecules move rapidly and randomly
• Distance between gas molecules is greater than diameter of molecules ∴ volume is negligible
• No forces of attraction/repulsion between molecules
• All collisions between particles are elastic therefore Kinetic Energy is conserved
• Temperature of gas related to average Kinetic Energy of molecules

Conditions at which gases behave ideally:
• High temperature
• Low pressure

Limitations of Ideal Gas Laws:
Real gases do not obey kinetic theory in two ways:
• There is not zero attraction between molecules
• We cannot ignore volume of molecules themselves

Deviations visible at Low Temp. and High Pressure:
• Molecules are close to each other
• Volume of molecules not negligible relative to container
• Van der Waal forces present, pulling molecules to each other
• Pressure is lower than expected from ideal gas
• Effective volume is less than expected from ideal gas
