The energy change can be regarded as being made up of three parts: the endothermic breaking of bonds within the solute and within the solvent, and the formation of attractions between the solute and the solvent.
Does not sound like mixing of gases. No bonds are broken. No bonds are formed. Just (almost) free molecules moving around.
As my profession is solid mechanics, mixing of fluids is not my field of expertise.
We are talking about mixing of gases, not the solution of a liquid in a gas or a solid in a liquid.
Here, no bonding forces are broken as there are almost none active. Air as a mixture of gases at low pressure is, at least like I have learned in thermodynamics, treated as if its different components don’t interact with each other. For each component, the state equation is evaluated individually using its partial pressure.
Of course. Otherwise this would qualify as a chemical reaction.
I’d totally get it, if were taking about lets say vaporising of perfume or fuel. There, the bonding forces between the molecules of the liquid (van der Waals, H-bridges) are released, and thus stored energy is set free.
I was focused on the marginal effect no matter how small, but you’re right that heat of solvation for gases is minuscule. I’m won over on the idea that it would be outweighed by cooling effect of gas expansion from fart decompression.
Qualifies mixing of gases as dissolution?

In a nutshell, the bonds in question are intermolecular forces, not bonds between atoms within a molecule.
Still not a solution.
Care to elaborate on your stance?
Each molecule is on its own. There is nothing to dissolve. No bonds to break.

Yeah, that’s fair.

Did you already find information on how much pressure a colon can sustain or maintain?
