Lyrics to a song that may be used as a humorous "tail" to a thermodynamics lesson or lab. You may sing it to Gershwin's "Summertime" from Porgy & Bess.

1. The Thermodynamics Song
With apologies to George and Ira Gershwin
Sung to “Summertime”

2. Delta H—is the change in en-thal-py
It's the energy change plus delta PV.
Your pressure's constant
In your Calorie-meter
So delta H, darlin', equals qp

3. One of these days, in a chemical system
There'll be a heat change we'll make equal to Q
Then the surroundings, which are aqueous, sugar,
Will change their kinetic. . .energy, too.

4. Entropy—drives spontaneous process.
It's a function of the possibilities
That a system can assume, and I tell you
It will not decrease without messes of energy.

5. Delta Gee is a critical function
It is delta Aitch less T delta S
And its value, speaks of favored/not favored
It makes equilibr'um constants, Oh---yes!
