The Third Law of Thermodynamics: Absolute Zero
Brr, it's so cold today! Could it get any colder? Is there a coldest possible temperature? Yes, there is! That seems strange, but now we know that temperature is just a measure of kinetic energy, so zero kinetic energy must mean zero...

Practice Problem: Density of a Gas
If we can use the ideal gas law to find the molar mass of a gas and therefore identify the gas, what can we do with the density of a gas? Well, pretty much the same thing, it just involves one extra calculation, so let's give it a try!
