'Twas the night before thermo, when all through the class,
Not a student was sleeping, all afraid they wouldn't pass.
The p-sets were placed on the table with care
In hopes that the answers soon would be there.
Raymundo was nestled all snug in his bed,
With no thermodynamics worries in his head,
And Mrs. Carter in her 'kerchief, and Carter in his cap,
Had just settled down for a long winter's nap,
When in my head there arose such a clatter,
I sprang from my desk to figure out the matter
When what to my wondering eyes should appear,
But a phase diagram -- it was all so clear
With a triple point and even all of the phases,
I knew in a moment I must count my graces.
More rapid than eagles my answers they came,
And I whistled and shouted and called them by name;
"Now D, now f, now 2 and C!
On a graph, on axes with P and T!
On to the top of the paper, to the top of the wall,
Now diagram, diagram, diagram all!"
So on the paper, the answers they flew,
With the number of components, and phases too.
And then in a twinkling, I knew the degrees of freedom,
It was so easy, I thought only I could be so horribly dumb,
For in my head, I remembered the key;
that D plus f equals 2 plus c.
With that, I finished my answer, excited I'd gotten it right
And heard Carter exclaim, "Remember the Gibb's Phase Rule, and to all a good night!"
