No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

No no, dissolution does generate (sometimes negative) heat. It's called heat of solvation and it exists because when something dissolves it breaks solute-solute bonds, requiring energy, but then forms solute-solvent bonds, releasing energy. This difference can either result in the solution becoming hotter or colder than its components.
This is not happening here. There is no solution, everything is a gas.
Yeah solutions can have any phase of solute and any phase of solvent. The most common example of a solution of gases is the air, so yeah.
No. Gas in gas can not be a solution. The solvent must be a solid or liquid.
Okay this is apparently one of those things where you'll get different answers depending on who you ask (even different Wikipedia articles give different answers), but this is a matter of semantics. No matter what you call it, mixing on a molecular level will result in the release or absorption of (in the case of gases a very small amount of) heat.
The edge cases, so mixing very polar with very nonpolar gases has deviations in enthalpy. Very tiny, but they exist.
Mixing inert species like nitrogen, CH4 or oxygen (anything human, fart or air related) does not result in a change in enthalpy. All it does is increase entropy. They are essentially ideal gases under these conditions, nothing happens.
Which Wikipedia article? Please name them so they can be corrected.
Heat does not get absorbed. Semantics or not, these words have well defined meanings.
