Edited to give a real answer~ Gases can/do store energy and that energy can be harnessed via chemical reactions like burning. A “calorie” technically speaking is short hand for the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius. You’ve probably heard the term BTU before too, same thing but much bigger. A BTU (British thermal unit) is the energy it takes to raise one pound of water one degree F. Whether or not a person can absorb that energy is a different matter all together. I have no idea about the nutrition side of it all. But, yeah, sure, calories can be stored in gaseous elements.
I think the question is if calories can take the form of a gas like it can solid or liquid. Like, just by breathing them in somehow.
Yeah, I decided to actually answer, it is a question from my wheelhouse I guess.
Calories are not “a thing” but a measurement unit for energy. So yes. everything “has calories”.
Everything with energy, sure… But I’m not sure that all matter has energy. Water, for example, has zero calories/energy. In fact, cold water effectively has negative calories as your body has to use energy to bring itself back up to temperature.
Yes. Natural gas, used in stoves and heating systems, is a good example.
I used to joke that I would cheat on my diet by sniffing freshly baked pastries… Say it ain’t actually so!
I don’t think you can just aerosolize a cheeseburger and inhale it to replace a meal, if that’s what you’re asking.
Ethanol has caloric value and you can absorb it by breathing, not sure what other substances that applies to though.
Well… 80% of the weight humans lose is lost through the breath as CO2… Does that count?
