1 Combined Gas Law Avogadro’s Principle

2 2-Variable Gas Laws Boyle’s Law: Charles’s Law: Gay-Lussac’s Law:
P1V1 = P2V2 Charles’s Law: 𝑉1 𝑇1 = 𝑉2 𝑇2 Gay-Lussac’s Law: 𝑃1 𝑇1 = 𝑃2 𝑇2

3 Combined Gas Law P1V1 T1 = P2V2 T2
Combine the relationships of the 3 gas laws to relate Pressure, Temperature, and Volume for a fixed amount of gas P1V1 T1 = P2V2 T2

4 Combined Gas Law Example
A gas at 110 kPa and 30.0°C fills a flexible container with an initial volume of 2.0 L. If the temperature is raised to 80.0°C and the pressure increased to 440 kPa, what is the new volume?

5 Avogadro’s Principle V1 n1 = V2 n2
Equal volumes of gases at the same temperature and pressure contain equal numbers of particles. V1 n1 = V2 n2 1 mole of any gas occupies a volume of 22.4 L at STP.

6 Avogadro’s Principle Example
Calculate the volume that moles of any gas at STP will occupy.
