User blog:Mr. Bambu/D&D Homebrew Calc: Liquefying the Big Boye

Premise
I told DMUA about this story. A long while back, when Mogar could fly, he went on a little split-up adventure with a character named Karin'Tir, up a chute in the roof in a desert pyramid. Up that chute was a huge iron golem with a living heart. While it nearly killed Karin'Tir, we managed to get a mage in to assist, and he cast Power Word: Liquefy on it.

Liquefying that would be a helluva feat. Let's go.

Calc
A normal Iron Golem, which we were told was dwarfed by this creature, takes 5000 pounds of iron to craft. We will assume this takes 3x that, as it dwarfed a mundane one. So 15,000 pounds of pure iron. So 6803.89 kg.

We will need to calc both the melting of this iron and the change in state of matter.

Temperature to Melt Iron: 1538 C

Specific Heat of Iron: 460 J/(kg x K)

Average Temp: 16 C (so change in heat was 1522 C)

Energy = mass x specific heat x heat change = 4.814e9 Joules

Heat of Fusion of Iron = 247112.54

Energy of Fusion = 1.681e9 Joules

Total Energy Output = 1.681e9 + 4.814e9 = 6.495e9 Joules, or Building level+

Well below expectations. Oh well.

Tally
Golem Is Liquefied: 1.55 Tons of TNT, Building level+
