So you have it boil water by specifying the number of Joules to use? Or kilocalories?
What even is this line of reasoning? Outside of a lab, I don’t need to know the amount of energy used to boil water. That’s the point. It’s boiling when it boils.
And 100°C isn’t even the boiling point of water at altitude. It’s a totally arbitrary scale, not very useful in day-to-day situations.
If you’re going camping with a solar battery and an electric kettle, you absolutely need to know a ballpark of how much energy it takes to boil a cup (250ml) of water, or you won’t get your morning coffee.
It’s also important information if you’re living off grid, running a desalination plant, sending a mission to Mars, operating a nuclear reactor, building a jacuzzi, or studying the mantis shrimp.
You’ve got to almost admire the “well I don’t do anything that requires precision or collaborating with others, so eyeballing my own body parts should be fine for everyone” attitude there…
Well yeah, stove kettles are a century out of date, for a start.
I presume you use an electric kettle, then?
