How heavy can I make water?

[TheEldritchGod]

You know the drill. I got Elemental Water powers. I make water with magic. Poof

So I was thinking, how heavy is that water? Well... it's most likely Oxygen-16, Hydrogen-1

Assuming I had the ability to cherry pick my isotopes, what is the heaviest water I could make and how much more heavy would it be compared to normal water. I would like the radioactive and non-radioactive examples. Note, it would have to exist for more than a few seconds.

Right Now, Assume it 0xygen-16 and Hydrogen-1 is the base. I think, stable-wise, I could get H-3 and Oxygen-18, for an extra 6 neutrons per water molecule.

But Oxygen-22 has a half-life of 2.25 seconds, so half the O-22 would be gone in 2 seconds, but 0-22 as a half-life of 13.51 seconds so that should be long enough. H-4 (tritium) has a half-life in years, so that works, but every other hydrogen isotope has a half life in picoseconds.

So I think weight wise, I have 18 vrs 24 (stable) vrs 28 (radioactive)

or 33% heavier / 56% heavier

So, If I had dueling water elementalists, would there be a significan advantage to making my water out of heavier isotopes when I hit someone with an ice spike?

Note, I already determined that the best Ice to make is Ice-7, which is stable at room temperature... and at about 40,000 atmospheres. It is 180% the density of normal ice.

Couldn't the water just be compressed enough and it would get heavier? Though if the compression is too much it might create a fusion reaction.

Yeah, but once you reach Ice-7, you really cannot compress it anymore. If you do, it stops being water. Ice-7 is basically Ice compressed to the point it is doubled up. So you have two interlacing "sets" of ice intertwined.

[RepresentingPride]

I don't understand all those scientific terms but there planets out there who are purely water. So you can literally drop a planet of water (including her weight) with your magic *poof*.

Exactly, hydrogen would become helium and oxygen florine and a lot of energy would be released.

This is an interesting idea.
I think you will gain a functional advantage, but only if moving the water they create takes a minimal increase in mana to move increased density of water. Or if an avatar the last airbender type deal, then a minimal amount of movements. Or cultivation and qi... etc.Otherwise it might end up going comically slow.

 

[melchi]

It could be an interesting twist where a water mage tries to compress water to an extreme only to discover that they have no power over it the moment it stops being water.

 

[Prince_Azmiran_Myrian]

Just change the definition of water and you can make it however heavy you want it to be. If heavy even has the same definition as normal.

Heavier ice spike will perform better against armored target but need longer run up to reach max velocity.

Liquid water is denser than solid ice so you can make an liquid filled ice spike too lol

oooo... supercooled water that freezes when pressure is released... interesting.

Not the point.

About 30%. That's tritium 3H(Hydrogen with to extra neutrons) with 18O (Oxygen with 2 extra neutrons).

It's a known value for heavy water to nuclear peeps.

If ice 7 is unstable at atmospheric pressure, you can also spawn it and immediately pop it in the face of the target

In regards to heavier water being an advantage between two water manipulators, I expect the biggest advantage would not be that the water is heavier, but rather acts in ways that the opponent does not expect, should they try to wrestle control of it. And if you can keep anything at 40,000 atmospheres, no need to bother with the ice spike, just crush what ever gets in your way in your watery pressure chamber of death. Or like uwutrucked said:

If ice 7 is unstable at atmospheric pressure, you can also spawn it and immediately pop it in the face of the target​

You could use your super pressured ice/water as bombs.

While making the water heavier ala isotopes would be a neat gimmick I don't see it making much of a difference as the same effect could be achieved by simply adding more water, something the characters could assumable easily do. Or by adding salt or some other dense solute to the water, although I assume they can only summon water and not Brine, but if somehow they can summon the saltiest of salt waters, brine can reach densities of 2.28 grams per cubic centimeter (which is 2.28 times pure water's 1 gram per cubic centimeter) So that would give more weight than isotopes and be more stable, but it would require the need to be able to summon salt/salty water.
I imagine heavy water could be an advantage in that it takes more effort to manipulate, making it good for training, some one who trains using tritium 3H would have better endurance/control over large amounts of normal water than someone who did not do this heavier training.

If you hit someone with a heavier isotope ice spike, beyond the extra penetrative power it would have from more mass, I think the main advantage would be 1. It is different from normal water and thus maybe the target would have a hard time/be unable to divert the projectile's course if the target was some one who had the power to manipulate water. and 2, after its stabbed into the target, the shock of the blow + it not being easily manipulated out of the would/what ever they would want to do it an ice spike embedded in them with their powers, may cause them to panic.

But yeah circumstantial, total water manipulation is already so incredibly strong making your projectiles use denser water isnt really worth thinking about.

Water basically cannot be compressed. The difference in density on surface of the ocean and at the bottom of the Mariana trench is something negligeable.

Add all of the speed.

After having fought the demon lord, he managed to figure out how the demon lord uses "fire and forget" magical attacks that include a small amount of mana to maintain stability. In short, he shoots a sheath of mana to maintain the ice-7 until it connects with the target.

I assume they can only summon water and not Brine

Indeed. Gotta have those limits.

I imagine heavy water could be an advantage in that it takes more effort to manipulate,

Yeah, there's a number of effects I'm thinking of. Basically it's an engineer taking water manipulation into strange directions and trying to break physics. For example, if he were to go with a really high isotope of oxygen, it would decay almost instantly into florine, which, if in the right proportions, would combine with the hydrogen inside a sheath of normal water to become hydrofluoric acid. So he's upgrading from bolts of exploding ice to bolts of exploding ice that turn into a cloud of acid. There's a point to his obsession with upping the damage of his attacks constantly.

(because its gonna come back to haunt him. heh.)

Note, physics is kinda screwed up. Don't want to spoil the reason why, but electromagnetism is kinda borked.

Although, if he makes oxygen-15, it emits positrons when it decays. I'm trying to figure out if that would rip a hole in reality or not. Most universes are way too far away from dark matter for any amount of antimatter to be "stable" and occur naturally. Well, as stable as it in the "real" world, that is.

Like, uh at least 5 heavy

 

[melchi]

Also, there are some other heavier isotopes of water but they have a really short decay time.

https://en.wikipedia.org/wiki/Isotopes_of_oxygen

This might actually be deadlier than just density. I don't know if Oxygen is an alpha particle emitter when it sheds parts but inhaling or ingesting an alpha particle emitter is about the worse form of radiation poisoning one can get.
