Gas Laws Foldable
First, fold your paper in half like this. Not this.
Cut only the top half of the folded paper. You need six “flaps.” Cut only the top half of the folded paper.
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
Under flap 1 – Boyle’s Law V ↑ P ↓ V ↓ 1 2 3 4 Pressure and volume vary inversely when temperature remains constant
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
Under flap 2 – Charles’ Law T ↑ V ↑ T ↓ V ↓ 1 2 3 4 Temperature and volume vary directly when pressure remains constant
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)
Under flap 3 – Gay-Lussac’s Law T ↑ P ↑ T ↓ P ↓ 1 2 3 4 Pressure and temperature vary directly when volume remains constant
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)
Under flap 4 – Combined Gas Law 1 2 3 4 Pressure, temperature, and volume can all change with the following equation.
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)
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
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
Under flap 6 – Ideal Gas Law A law relating pressure, temperature and volume of an ideal gas 3 4 5 6
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.
