This song outlines the kinetic-molecular theory of ideal gas behavior, Avogadro's Hypothesis and deviations from ideal gas behavior. All music and lyrics copyright 2005 by Mark Rosengarten. All rights reserved.

Lyrics:

Gas is made of molecules that are far apart and small
They dont lose their energy when they hit container walls
They travel in a straight line, no changing from their course
They move faster when its hotter, they have no attractive force!

Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!

Gases that behave like this are often called ideal
Which gases are most like this, though they are very real?
Hydrogen and helium, the smallest gases on the chart
High temperature, low pressure will spread them far apart!

Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!

Assume all gases behave like this, treat all them the same
Its Avogadros Hypothesis, theyve given it a name
Equal volumes of different gas, if they have the same T and P
Will have the same number of molecules of gas in each, you see!

Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!

The mass of each gas molecule is weighed in a.m.u.s
We need to turn that mass to grams which we can better use
You need Avogadros Number, thats something that weve heard
A mole is six point-oh-two times ten to the twenty-third!

Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!

Because we treat each gas the same, each one thats on the list
(Real gases have attractive force, pretend they dont exist)
We can use the Gas Laws with each and every one
So go get your calculator out and prepare to have some fun!

Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!

Whether you use Boyles Law, or Charles or Gay-Lussacs
You can use them on ANY gas, and you wont get no flack
Thanks to Avogadro, we can treat them all the same
And that is why I wrote this ditty in honor of his name!

Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!
Rock me Avogadro! Rock me Avogadro! Rock me Avogadro, with gas laws!
