Gay-Lussac’s Law

For lesson 59, we learned about Gay-Lussac’s Law (P=kT), the third gas law needed to connect pressure, volume, and temperature.  Gay-Lussac’s Law helps explain the egg-in-a-bottle trick, where boiled water displaces the air inside a bottle, and as the water condenses, an egg placed over the bottle will be pulled inside because of the change in pressure inside the bottle.

The Lesson 59 worksheet and Lesson 59 PowerPoint are available for download.  By the end of class tomorrow, students should be able to explain the outcome of the experiment below using Gay-Lussac’s Law:
