Study Notes
- Ideal Gas Laws: Boyle's Law and Charles' Law
- Boyle's Law: For constant temperature, pressure of an ideal gas is inversely proportional to its volume.
- Holds for perfect gases, doesn't depend on mass.
- Applicable to isobaric, isothermal, and isochoric changes.
- Charles' Law: For constant pressure, volume of an ideal gas is directly proportional to absolute temperature.
- Avagadro's Hypothesis: At constant temperature and pressure, equal volumes of gases have equal numbers of molecules.
- Ideal Gas Equation: Equation of state for ideal gases.
- Ideal Gas & Real Gas: Differences between ideal and real gases according to Kinetic Theory of Gases.
- Kinetic Theory of Gases: Postulates explaining gas behavior.
- Root Mean Square Velocity: Speed measurement of gas molecules.
- Mean Free Path: Average distance traveled by a gas molecule before colliding with another.
- Ideal Gas Laws and Kinetic Theory of Gases interconnected through molecule behavior and gas properties.
