The volume of a gas maintained at a constant temperature and pressure, is directly proportional to the number of moles of the gas.
Avogadro’s Law
Tool used to measure atmospheric pressure
Barometer
The volume of a dry gas is inversely related to the pressure if the temperature is held constant. (PV=k)
Boyle’s Law
When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume are directly related. (V/T=k)
Charles’s Law
Combination of 3 Gas Laws . (PV/T=k)
Combined Gas Law
High pressures can squeeze gases into smaller volumes
Compressibility
The total pressure of a mixture of gases equals the sum of the partial pressures
Dalton’s Law of Partial Pressures
density= molar mass/ molar volume
Density Calculation
When a gas spreads out to fill the entire volume of a container
Diffusion
Gas particles can pass through tiny openings
Effusion
When gases experience lower pressure, they quickly expand to fill the available space
Expansibility
Gas particles that are able to glide past one another like particles of liquid
Fluidity
Pressure is directly proportional to temperature in kelvins for a fixed mas of gas held in a constant volume. (P/T=k)
Gay-Lussac’s Law
A gas whose behavior is perfectly predicted by the kinetic- molecular theory
Ideal Gas
Gas particles are tiny compared to the great distance between them and particles do not interact with each other or the walls of their container except during momentary collisions
Kinetic- Molecular Theory
