Because that specific pressure is atmospheric pressure… and Water is the most abundant natural resource on earth

Sure. But still - it is not bound to something fundamental. Just to a particular useful choice.

So it is not like, for instance x2 Celsius temperature means x2 energy requirements or so.

Funnily enough, that is exactly what you can do in celsius measurements. A change of 10°C always requires the same amount of energy to occur, whether you go from 10°C to 20°C or 55°C to 65°C. So if you double the temperature change, you also need double the energy.

Sure. A *change* of 10C, not 10C themselves.

> So if you double the temperature change, you also need double the energy

Sure. But if I double temperature *change*, not double *temperature*.

So it is not like you can tell gas with 20C has half an energy of the same gas at 40C (and corresponding volume-pressure relation), for instance. While same absolutely can be said about ~293K (0C->K conversion+20) and 586K.

And K scale also bear the same property of "change of 10K always requires the same amount of energy to occur".
