Study Notes
Gas Parameters
- A gas sample is described by four measurable properties: volume (V), pressure (P), temperature (T), and number of moles (n) of gas.
Gas Classification
- Gases are classified into two types: ideal gases and non-ideal (real) gases.
- Ideal gases obey general gas laws.
- Non-ideal gases do not obey general gas laws.
Gas Laws
Boyle's Law
- States that the volume of a gas at constant temperature is inversely proportional to its pressure.
- Mathematically represented as V ∝ 1/P.
Charles' Law
- States that at constant pressure, the volume of a gas is directly proportional to its absolute temperature.
- Mathematically represented as V ∝ T (at constant P).
Law of Pressure
- States that at constant volume, the pressure of a gas is directly proportional to its absolute temperature.
- Mathematically represented as P ∝ T (at constant V).
Avogadro's Principle
- States that at constant temperature and pressure, equal volumes of gases contain equal numbers of molecules.
