Thermodynamics Chemistry Song

Bored one spring break, I made this up for a chem project.
Yup. I am that cool.
To the tune of "Low", by Flo Rida
I'm quite proud of the lyrics. But I can't listen to the original song without singing my words. Also, I'm not incredibly proud of the fact that I actually sang it. And it sounds like PAIN. Not T-Pain. Just PAIN. (It can be debated if those are synonymous, however.) I had to bribe a friend with an entire bag of Butterfingers to sing it with me so at least I had someone with whom I could sound like an idiot. Idiocy is always better with a friend! But here. Here is the song.


CHORUS:

We’re talkin’ ‘bout thermochemistry
With heat and temperature
To measure change in heat we use a calorimeter
C subscript p
Means specific heat
And it equals q over mass times delta T

Delta H is change in enthalpy
Amount of lost or absorbed heat
‘Cuz enthalpy is all about heat energy
When delta H is exo (thermic)
It’s below zero,
Enthalpy’s low, low, low, low, low, low, low, low

VERSE:
Delta S is change in entropy
It’s a measure of anarchy
When the particles are goin’ all crazy
You got positive entropy
Nature likes mess, and likes unrest
Like in a gas, that’s delta S
Hold up wait a minute, we gonna talk about somethin’ else

Ima tell you bout delta G
Change in Gibbs free energy
A function of enthalpy and entropy
It’s a measure of spontaneity

There is a formula for delta G:
Delta H minus delta S times T
When it’s negative it fills us with glee
‘Cuz then the reaction can happen…wheeee!

Could You Care Less?

I have noticed that quite a lot of people have been incorrectly saying "I could care less" when they really mean "I couldn't care less". This could cause some major misunderstandings; just imagine: you're talking to a horrendously dull and boring man. You are late for a meeting. You say "I could care less". He earnestly thanks you for finding his story about his socks so fascinating and drones on for the next three days, preventing you from eating, drinking, or micturating. This is what we want to avoid. Therefore, I have devised a diagram to help you to never find yourself in the aforementioned situation. Plus, it angers ME when you do this wrong.
