Lets return to that graphic organizer….

TPS How could we combine these three laws so that each relationship is still represented? We are looking for ONE equation.

The Combined Gas Law!

allows us to do calculations for situations in which only the amount of gas is constant We see changes in our 3 variables at once We have been using it all along! (You just held certain variables constant)

Things to remember: Keep units consistent (start to finish) Kelvin…..Always.

Lets try a problem together: The volume of a gas-filled balloon is 30.0 L at 313 K and 153 kPa pressure. What would the volume be at standard temperature and pressure (which is 273K and kPa)

Pair Problems: A gas at 155 kPa and 25°C has an initial volume of 1.00 L. The pressure of the gas increases to 605 kPa as the temperature is raised to 125°C. What is the new volume? A 5.ooL air sample has a pressure of 107 kPa at a temperature of -50°C. If the temperature is raised to 102°C and the volume expands to 7 L, what will the new pressure be?

Lets Share those results:

One for a challenge: The volume of a gas at 26°C and 75 kPa is 10.5 L. The pressure is increased to 115 kPa. What final temperature would be required to reduce the volume to 9.5 L?

One for a challenge: The volume of a gas at 26°C and 75 kPa is 10.5 L. The pressure is increased to 115 kPa. What final temperature would be required to reduce the volume to 9.5 L? 418 K
