It’s about 1 BTU per fluid ounce per degree Fahrenheit, so:

128 fl oz × (212 - 68)°F × 1BTU/fl oz•°F = 18,432 BTU

Add in the enthalpy of vaporization:

7.5 BTU/fl oz × 128 fl oz = 960 BTU

So, about 19,392 BTU.

I’m cooking pasta for dinner, and I didn’t do any calculations. I just put the water in the pot on the stove, and waited for it to boil. Which was kind of the point of my question. Metric is all neat and elegant, but that’s irrelevant in daily life, because if I did have to calculate the energy requirement, I’d have to look up the enthalpy value, because it’s not memorable, as well as figuring in the actual atmospheric pressure to determine the actual boiling temperature. It makes all the sense in the world to use SI where it matters (e.g. science experiments), but customary units persist because in so much of daily life, it doesn’t matter.

Why is the third sister, squash, given so little respect here?

Okay, then, how much energy does it take to boil 1mL of water from room temperature? (Note that I said “boil,” not raise it to 100°C.)

NOOO!!!

America has its own laws of thermodynamics!

If by “metric system,” you mean SI. But then, SI uses m³ for volume, not litres. The author didn’t specify which metric system, so this could be valid.

If there’s anything that I value most in my shitposts, it’s timeliness and accuracy. Now, I feel doubt creeping in… is horse plinko maybe not a real game?!
