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.
Yes. Natural gas, used in stoves and heating systems, is a good example.
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.
I used to joke that I would cheat on my diet by sniffing freshly baked pastries… Say it ain’t actually so!
Well… 80% of the weight humans lose is lost through the breath as CO2… Does that count?
