Twice as hot is also useful in Celsius. For every increase of 10C chemical reactions happen twice as fast, it will literally, thermodynamically be twice as hot.

Which will probably even match your subjective feeling.
Celsius scales thermodynamically logarithmically. You can’t just double the numbers. (The same with sound etc.)
- Certhas 3y agoReaction rates are approximately exponential in temperature, but there is nothing special about 10C. The doubling temperature difference depends on what reaction you look at. This is as opposed to decibel for sound, where +10 decibel means X10 power exactly.
- InitialLastName 3y agoTo be clear, that's true of power decibels for everything, not just sound.
- thfuran 3y ago>For every increase of 10C chemical reactions happen twice as fast Except for the ones that go at different rates.
- _Microft 3y agoThe Celsius scale is an "interval scale" while the Kelvin scale is a "ratio scale". One cannot take ratios of Celsius temperature values as ratios are not even defined for that. It’s possible for differences of temperatures on the Celsius scale, though. https://en.wikipedia.org/wiki/Level_of_measurement https://en.wikipedia.org/wiki/Level_of_measurement
