Gases
Characteristics of a Gas takes volume and shape of container compressible and expandable (distance between particles can change)
Gas Laws Ideal Gas Law: PV=nRT –Pressure –Volume –number of moles –R=universal gas constant –Temperature
Boyle’s Law P V T constant
Charles’s Law T V P constant
Gay-Lussac’s Law T P V constant
Avogadro’s Law For a gas at a constant temperature and pressure, the volume is directly proportional to the number of moles of a gas (doesn’t matter what kind of gas).
