What is pressure volume behavior
It is when you decrease volume, the number of collisions with the container will increase.

Charles’ Law
Temperature and volume are directly proportional at constant pressure
100
The Ideal Gas Law
Derived from experimentally based laws of Boyle, Charles, and Avogadro in 1834
Includes ALL variables
PV = nRT
200
What is Pressure
Pressure = Force / Area
Directly proportional to force applied and inversely proportional to the area upon which the force act

Gay-Lussac’s Law
Temperature and pressure are also directly proportional at constant volume.

The Ideal Gas Constant (R)
R = 0.0821

What is boyle's Law
Pressure and volume are inversely proportional at constant temperature
P1V1 = P2V2
300
Combined Gas Law
The effect of changing pressure and temperature or volume on a gas
P1V1 = P2V2

Nonideal Gas Behavior
All gas relationships we considered have related to ideal gases
Behave under all conditions as predicted by the kinetic molecular theory
At very high pressures and low gas temps, real gases do not behave ideally
What would these conditions do to a gas?

Temperatures in “Kelvin”
Kelvin is another measure of temperature, like Celsius or Fahrenheit
It is used in science because it does not include negative numbers
0 K is called absolute zero, the coldest temperature possible (-273°C)

Molar Volume
At conditions of 0°C and 1 atm, the volume of one mole of any gas sample is 22.4 L
No similar relationship can be drawn for the molecules of any solid or liquid

Dalton’s Law of Partial Pressures
The pressure of a mixture of gases is equal to the sum of the pressures of the individual gases
PTotal = Pgas1 + Pgas2 + … Pgasn
Pgas1 = (mole fractiongas1)(Ptot)
where mole fraction = mole of gas1
total moles of gases
