Eli5 Why 80 degree Celsius is not four times as hot as 20 degrees celsius?
In: 0
Because the true zero point is at -273°C. 0°C is just a random point chosen for convenience.
So if you double the true absolute temperature (wich is measured in Kelvin) at 0°C you get 273°C.
In Kelvin the temperature is a direct measure of how much energy there is. 0K would mean absolutely no energy (but that’s impossible to reach)
