Unit 3, Lessons 11 and 12

Lesson 11:

Gay-Lussac's law tells us that the pressure of a given amount of gas is proportional to its temperature and that the volume of that sample will never change. Temperature, usually expressed in Kelvin, plays a role in this equation:

k = P/T

where k is the proportionality constant, as it was in Boyle's law. A simpler way to describe this law, and if you could picture it on a graph you'd see why, is to say that as temperature rises, the pressure increases, and while the pressure decreases, the temperature drops as well.

Lesson 12:

This lesson was relatively self-explanatory. The kinetic outlook on gases tells us that gas molecules are already in motion--which we knew. We can take this outlook and apply it easily. The more pressure you put on a sample of gas, the more you restrict the movement of the molecules inside. When you release pressure, those molecules move around quicker, at greater distances and speeds, resulting in a more flowy...I guess that's the world...yeah, more flowy gas.
