Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded?
dgdft@lemmy.world 1 day agoIn a nutshell, the bonds in question are intermolecular forces, not bonds between atoms within a molecule.
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.
Yeah, that’s fair.
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.

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

Still not a solution.

Care to elaborate your stance?

Each molecule is on its own. There is nothing to dissolve. No bonds to break.

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.
