[Verse 1]
Every bond's a tiny vault with energy locked inside,
Snap it open, pay the toll, that's the breaking tide.
Stack a new bond, seal the deal, energy spills out free,
The gap between the cost and gain writes the whole decree.
[Chorus]
Downhill reactions tumble, shedding heat like rain,
Uphill ones go climbing, swallowing heat like grain.
Break a bond, you're paying rent, make one, you get paid,
Feel the difference on your skin, that's how the trade is made.
[Verse 2]
Methane meets the oxygen, a match sets off the show,
Carbon dioxide, water vapor, flames begin to grow.
Thermite eats the rust from iron, aluminum takes the lead,
Molten metal pouring out, a downhill burning deed.
Shake a pouch of iron dust, let the air come creeping in,
Slow and steady rusting warmth beneath your frozen skin.
[Chorus]
Downhill reactions tumble, shedding heat like rain,
Uphill ones go climbing, swallowing heat like grain.
Break a bond, you're paying rent, make one, you get paid,
Feel the difference on your skin, that's how the trade is made.
[Verse 3]
Green leaves catch the sunbeams, stuff them into sugar chains,
Photosynthesis climbs uphill, locking light in grains.
Crack an egg into the pan, it just sits there clear and cold,
Feed it steady heat to twist the proteins, watch it fold.
Both of these are endothermic, sipping warmth like tea,
Uphill battles store the energy nobody else can see.
[Chorus]
Downhill reactions tumble, shedding heat like rain,
Uphill ones go climbing, swallowing heat like grain.
Break a bond, you're paying rent, make one, you get paid,
Feel the difference on your skin, that's how the trade is made.
[Verse 4]
Old Lavoisier packed ice around a guinea pig one night,
Measured melted water, proved his breathing math was right.
Now we drop a sample in a jacket full of water clear,
One kilogram, one Calorie, one degree of rise is near.
Count the warming, count the cooling, numbers never lie,
Calorimeters read the heat that bonds release or buy.
[Bridge]
Gasoline and granola bars, dynamite and coal,
Every single one's a vault of bonds, energy's the goal.
Fuel burns downhill fast and loud, food burns slow and sweet,
Explosives drop their bonds so quick the whole room feels the heat.
Stable molecules sit calm, their bonds are tight and low,
Shaky ones are itching for a downhill place to go.
[Outro]
Break a bond it costs you, make a bond you gain,
Count the heat with water, figure out the chain.
Downhill gives you warmth, uphill makes you wait,
That's the energy story written in every state.
