4 Gaseous State Flashcards
Assumptions of the Kinetic Theory
- Gas particles are in constant random motion
- Gas particles have negligible volume/size compared to the volume of container
- Gas particles exert negligible intermolecular forces on one another
- Collisions between gas particles are perfectly elastic
- Average KE directly proportional to absolute temperature (in K)
1 atm
101325 Pa
Conversion from Kelvins to Celsius
T (K) = T (°C) + 273
Ideal gas equation
pV=nRT
Boyle’s Law
Constant temperature, volume of a fixed mass of gas is inversely proportional to its pressure (pV=constant)
Charles’ Law
Constant pressure, volume of a fixed mass of gas is directly proportional to its absolute temperature in K (V/T=constant)
Avogadro’s Law
Constant temperature and pressure, volume of a gas is directly proportional to the number of moles of gas (V/n=constant)
Dalton’s Law of Partial Pressure
Total pressure of a mixture of non-reacting gases equals to the sum of the partial pressures exerted by the constituent gases.
Deviation of ideal behaviour
- High pressure
- Large electron cloud/polar (stronger imf)
- Lower temperature
