Water actually has shitty electrical conductivity.

Just curious, have you watched the show with the same name as your account?

I guess it’s for kids to help them deal with trauma. I downloaded it due to super high ratings, but I haven’t watched it yet (and might not; I don’t have or want kids, but I like having good stuff for friends with them)

But then the conductivity perishes as the salt is being spent. Just add more salt, then?

What would a CPU look like with these wires? Would it fit within my town?

This is false. the correct number is approximately 93%.
About 7% of everyone who ever lived is still alive.

Still, you're doing remarkably well for only having drunk water once.

they all are chronically ill, they will die, just in some time

I have ingested it, and I haven't died.

I've always hated "incompressible" when talking about fluids. It's just shorthand for: doesn't compress much under pressure.

In engineering unless you're dealing with insane pressures, when something is "incompressible", assuming it is is good enough.

But it's still misleading so I don't like it haha

Dissolves everything? Hydrophobic and halogenated compounds would like to have a word.

Fun fact, there are materials that dissolve better in fatty acids than water. For example, Menthol crystals extracted from Mint Oils will readily dissolve in other oils but is very picky about its water.

Idk, have been statistically proven that everyone who come into touch with that material end up dying.

True, but we also tested many other materials across thousands of years and the death rate of contact with dihydrogen monoxide only exceeds the baseline death rate with immersion of the oral and respiratory sections of the visage. A property shared with most other substances, especially in liquid forms.

I've noticed that the nerd meme communities here are just as, if not more, pedantic than the ones on reddit

Edit: oh yea that's also literally the first thing I thought when I read the post, whoops, I'm also a pedantic nerd, I just didn't bother commenting it

Some of us don't want to feel superior, we just want to share.

Not me though. I'm better than all of you. /joke

Pure water isn't a good conductor, it needs other stuff mixed in to be a good conductor. Not sure why they deleted their comment. They weren't the one being pedantic, they were complaining that other people in this thread had no sense of humor for calling out the mistake in the original pic.

Along with the people pointing out conductivity.

Who says water is not compressible? Takes a lot of energy, but the big bang didn't happen in a sea of water.

My oceanography textbook said so. You'd think the ocean people knew about water. Must be more propaganda from big compress to sell more compression.

Yeah, it's been 15 years since I've taken oceanography, but the density of water is determined by its temperature.

1
lemmy.world

Density is certainly changeable in water with temperature, but density isn't exactly the same thing as compression.

TIL A waterjet cutter pressurizes the water to something like 90,000 psi and it gets about 14% more dense. I always thought those things just had the water highly pressurised, but not actually compressed.

5

I want to posit that because water isn't compressible at forces we experience commonly, it doesn't mean it isn't compressible. For 99.999% of the water rules we concern ourselves with water should be considered incompressible, but there are exceptions to every rule

3

To be fair, ive seen what the ocean can do to carbon fiber tubes. If it can do that and still not compress, its pretty damn incompressible.

1

most solids and liquids are practically incompressible (when comparing with gasses). there is a relationship between bulk compressibility, shear stress and youngs modulus for solids, which can be extended for liquids. It does not work for gasses

In the middle I was thinking "Woah, 4 MJ/m^3? That's nearly the same as water!"

You got me, xD
