Gas Laws Foldable
2
First, fold your paper in half like this.
Not this.
3
Cut only the top half of the folded paper.
You need six “flaps.” Cut only the top half of the folded paper.
4
Dalton’s Law of Partial Pressures
There are six flaps of information. Label the top of your flaps like below: Boyle’s Law Charles’s Law Gay-Lussac’s Law Combined Gas Law Dalton’s Law of Partial Pressures Ideal Gas Law
5
Under flap 1 – Boyle’s Law
V ↑ P ↓ V ↓ 1 2 3 4 Pressure and volume vary inversely when temperature remains constant
6
Under flap 1 – Boyle’s Law
P1V1 = P2V2 1 2 3 4 Pressures need to have the same units Volumes need to have the same units
7
Under flap 2 – Charles’ Law
T ↑ V ↑ T ↓ V ↓ 1 2 3 4 Temperature and volume vary directly when pressure remains constant
8
Under flap 2 – Charles’s Law
V1 T1 V2 T2 = 1 2 3 4 V1T2 = V2T1 Volumes need to have the same units Temperatures both need to be in K (not °C or °F)
9
Under flap 3 – Gay-Lussac’s Law
T ↑ P ↑ T ↓ P ↓ 1 2 3 4 Pressure and temperature vary directly when volume remains constant
10
Under flap 3 – Gay-Lussac’s Law
T1 P2 T2 = 1 2 3 4 P1T2 = P2T1 Pressures need to have the same units Temperatures both need to be in K (not °C or °F)
11
Under flap 4 – Combined Gas Law
1 2 3 4 Pressure, temperature, and volume can all change with the following equation.
12
Under flap 4 – Combined Gas Law
P1V1 T1 P2V2 T2 = 1 2 3 4 P1V1T2 = P2V2T1 Pressures need to have the same units Volumes need to have the same units Temperatures both need to be in K (not °C or °F)
13
Under flap 5 – Dalton’s Law of Partial Pressures
The total pressure of a gas is equal to the sum of the partial pressures of the individual gases 3 4 5 6
14
Under flap 5 – Dalton’s Law of Partial Pressures
PT = P1 + P2 + P3 + … 3 4 5 6 All pressures must have the same units © Carey Munoz
15
Under flap 6 – Ideal Gas Law
A law relating pressure, temperature and volume of an ideal gas 3 4 5 6
16
Under flap 6 – Ideal Gas Law
PV = nRT P is pressure (atm, kPa, mmHg, torr) V is volume (mL, L) n is number of moles R is Ideal Gas Law Constant T is temperature (K) 3 4 5 6 Choose the R value based on the units for pressure.

Back side of foldable – Some helpful conversion factors & constants
Standard Pressures 1 atm 760 mm Hg kPa 101,325 Pa 14.7 psi 760 torr Common Volume Conversions 1 L = 1000 mL 1 cc = 1 mL = 1 cm3 Ideal Gas Constants (R) R= L*atm/mol*K R = 8.31 L*kPa/mol*K R = L*mmHg/mol*K R = L*torr/mol*K Temperature Conversions K = °C + 273 °C = (°F – 32)
