1 Combined Gas Law Avogadros Principle

2 2-Variable Gas Laws Boyles Law: P 1 V 1 = P 2 V 2 Charless Law: Gay-Lussacs Law:

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

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 Avogadros Principle Equal volumes of gases at the same temperature and pressure contain equal numbers of particles. 1 mole of any gas occupies a volume of 22.4 L at STP.

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