1. Daltons Law of Partial Pressures The pressure of a gas is equal to the sum of all of its components. P total = P gas#1 + P gas#2 + P gas#3 +…. [http://www.space.gc.ca/asc/img/neemo_daltons_law.gi]f All in kPa

2. Boyle s Law When temperature is constant, pressure and volume are inversely related. P 1 V 1 = P 2 V 2 http://wps.prenhall.com/wps/media/objects/476/488316/Instructor_Resources/Chapter_11/FG11_13.JPG Click Here for a Demo

4. Boyle s Law If a weather balloon has a volume of 15.0 L at a pressure of 1.20 atm, and the pressure drops to 0.750 atm, what is the new volume? (15.0 L) (1.20 atm) = (0.750 atm) V 2 V 2 = 24.0 L

5. Charles s Law When pressure is constant, the temperature and volume are directly related. http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter09/Text_Images/FG09_07.JPG Click Here for a Demo

7. Charles s Law If a car tire has a volume of 2.50 L at 15.0 º C and is heated to 65.0 º C, what will be the new volume?

8. Combined Gas Law Useful connection between Boyles & Charless Laws…

9. Combined Gas Law Example: (Charless Law) T 1 = 273 K, V 1 = 1.00 L, T 2 = 373 K Pressure is held constant so just remove it from the equation…. V 2 = 1.37 L

10. Combined Gas Law Example: (Boyles Law) P 1 = 1.00 atm, V 1 = 1.00 L, V 2 = 3.00 L Temperature is held constant so just remove it from the equation…. P 2 = 0.333 atm
