Explaining the Behavior of Gases
The constant motion of gas particles allows a gas to expand and fill its container.
Gases have very low density
Gases can compress or expand.

Diffusion and Effusion
Diffusion -- the random mixing of gases due to particle motion until they are evenly spread.
Effusion -- the movement from an area of higher concentration to an area of lower concentration.
9
Graham's Law
Graham's Law of effusion states that the rate of effusion for a gas is inversely proportional to the square root of its molar mass.

Gas Pressure
Pressure is defined as force per unit area.
15
Measuring Air Pressure
A barometer is an instrument used to measure atmospheric pressure.
16
Measuring Air Pressure cont.
A manometer is an instrument used to measure gas pressure in a closed container.
17
Units of Pressure
The SI unit of pressure is the pascal (Pa). One pascal is equal to a force of one newton per square meter: 1 Pa = 1 N/m2
Typically, air pressure is measured in atmospheres in chemistry.

Dalton's Law of Partial Pressures
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture.
