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.

I cannot discern the difference between my arguments and yours. You just used more words? We're saying the same thing, except I was making a joke about pedantry.

You’re correctly identifying thermal mass as why they feel cooler to the touch, but this is mixed up in some incorrect and contradictory statements. You seem to keep changing your reasoning behind why tiles feel cooler to the touch.

The ceramic tiles in your house aren't really "colder" than you

This is incorrect, and why I replied to begin with.

Flooring is colder than your skin, regardless of the material, unless your floor temp is above 92℉ (33.5℃). You can measure this with a thermometer. If something is the same temperature as your skin you won’t feel anything - there’s no heat transfer. You could have a copper floor if it was the same temperature as your skin, you wouldn’t feel a thing.

[Ceramic tiles] also have a high thermal mass … they easily lose heat to the air. 

These two statements are directly contradicting one another. High thermal mass means it takes a longer time to lose heat to the air. Given identical conditions, ceramic will take longer to change temperature than fabric. For example, if you opened a window and it was 40℉ outside, the carpet would drop in temperature faster than the ceramic tile. It wouldn't feel this way to your skin, but it could be measured with a thermometer.

That thermal mass is why tiles feel cooler than carpet. Your body has no issue warming the fibers in carpet next to your skin to the same temperature as your skin, it's harder to warm up the tile because of the thermal mass.

Who do you keep bringing up the quote from the first reply.

They are literally colder than you. But i used the word really colder. The feel a lot colder than they should because of other phenomenon which we have covered at length and nothing of note was added. We are making the same point, chill out
