Gas Laws

Characteristics of Gases:
Gases expand to fill their container (no definite volume)
Gases are highly compressible
Gases form homogeneous mixtures
Gas molecules are relatively far apart from one another and exert little influence on each other (collisions are elastic)

You can measure pressure by using a barometer.

The ideal gas is at 1 atm and 0 degrees Celsius or 273.15 degrees Kelvin

Four factors which determine the state of a gas are:
-pressure
-temperature
-volume
-amount in moles

Boyle's Law:
Boyle's law doesn't boil! Temperature is held constant!
It tells us that the relationship between pressure and volume is an inverse relationship.
As we increase the volume of the container, there are fewer collisions with the sides, so we interpret that as a decrease in pressure. As volume increases = pressure decreases.
