A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

Yes, you can cool water for the exact same reason that it heats up really fast.
And yes, it kind of is like electricity, in fact, good conductors of electricity are generally good conductors of heat. Electrical conduction happens through transfer of electrons, so atoms that can easily gain/lose electrons conduct electricity really well. Heat conduction happens through kinetic energy transfer, and and free electrons can transfer that energy to adjacent atoms by moving between them (like they do with electrical energy). It's a very similar mechanism.
Water is a much better conductor of heat than air because it's much more dense. So if you have a metal tank full of water, the heat is much more likely to be conducted through the water inside the tank than the air outside the tank. That's why water cooling is so effective, it sucks the heat away from the hot component, transports it to a radiator, which then spreads out the water (dramatically increasing surface area) to maximize the effectiveness of transferring that energy to the air (more opportunities for the cooler air to collide with the warmer water molecules).
I think you might have a reading comprehension problem man.
Last words to that, hot stuff expands and gets lighter per 1cm³ so hot water flows on top all the time, heat always moves upwards rather than down. Electricity travels very differently than heat does, heat is atom speed and electricity is electrons jumping

That's just not true. Heat moves along the path of least resistance, not "up," "up" just happens to generally be less resistance than "down" due to density differences in air.
From your second link:
Density matters. Free electrons matter. But in short, metal and water conduct heat better than air, which means the heat transferred is more likely to go into the water than into the air. Certain metals conduct heat better than other metals, largely due to electrical conductivity.
