you're obviously not running experiments in a controlled setting because it doesn't
literally all of the water to ever enter your house has been boiled at some point, the molecules don't magically align a new way by being heated in the past 24 hours

Water from out of the tap is a mix of regular and heavy water (water made with deuterium instead of hydrogen). After the first boil, the heavy water is broken down into regular water, which by nature absorbs heat more easily due to the less dense atoms.

boiling water makes some of it evaporate so you'd be reboiling a smaller volume of water

Based retard.

>>15154477

it literally boils a signifigant faster rate

Record you whole experiment and upload it somewhere. I will point out possible flaws in the methodology, so that you can improve your measurements.

boiling water that boils faster than water that has never been boiled

So if I want to make my ramen faster I should just boil big batches of water at a time and then reboil them over the next couple of days? I eat about 4-5 packs of ramen a day. Just noodles, the seasoning and water. Thanks for your research, I do feel compelled to tell you that, indeed, I love science.

>>15154465
Previously boiled water had had a bunch of water evaporated and therefore has a lower volume so it takes less to to heat it to boiling.

now this is my kinda autism

>>15154465
Pure H20 does not boil faster after being previously boiled. Tap water contains many impurities in addition to H20. When you reboil tap water, the impurities concentrate further, which can be a health hazard.

>>15154525
using literally in a context-lacking phrase to imply multiple context sources is proper english ya fuckin' dropout

>>15154554
so double boiling is bad for your health?

>>15154564
someone better warn 4 packs of ramen a day anon

>>15154564
Yes, if your tap water contains any quantities of lead, arsenic, fluoride, nitrates, etc. Which basically all tap water does.

>>15154603
does the publick know about this

Also, let me precisely quote where you wrote this absurdity:
>After the first boil, the heavy water is broken down into regular water

>>15154522
For this reason, thermonuclear weapons are often colloquially called hydrogen bombs or H-bombs.

>>15154613

im scared

>There is a concern that reboiled water may lead a person to develop cancer. This concern is not unfounded. While the boiled water is fine, increasing the concentration of toxic substances may put you at risk for certain illnesses, including cancer. For example, excessive intake of nitrates has been linked to methemoglobinemia and certain types of cancer. Arsenic exposure may produce symptoms of arsenic toxicity, plus it has been associated with some forms of cancer. Even "healthy" minerals may become concentrated to dangerous levels. For example, excessive intake of calcium salt, commonly found in drinking water and mineral water, can lead to kidney stones, hardening of the arteries, arthritis, and gallstones

I'm guessing the molecular structure changes during the first boil
OP I use to play classical music to spring water to change the molecular structure. I would then freeze it and then thaw it.
I noticed that the thawing process took a lot longer to happen than when I didn't play music to it
but it was just something I noticed and did not do experiments with structurized and non structurized waters.

>>15154968
water is sertainly more complex then we initally thought

>>15154484
heavy water is toxic tho

>>15154968

>>15154465
water memory.
The water gets more and more efficient at boiling with each consecutive try. The effect is diminishes ofcourse.
Also shouting things like "BOIl FASTER YOU " .

maybe you were shaking the dissolved oxygen out of the water with the soundwaves
which is something that also happens when heating the water

How the fuck would boiling break down heavy water?

This nigga boiling water in a nuclear reactor.

boiling water makes it angry, this hot temper means it boils faster

>>15157453
this may been the most logical conclusion. you're angered the water demons

thissis gud thrade

>>15154465
Easy, water gets cheaper them more heat is involved.

Thats why you pay a dollar more for the cold beer up front by the counter.

>>15158175
then how come coors light is more expensive than regular coors, genius?

>>15158175
i drink my beer warm and its not cheeper

cold hurts my teeth

i also dont like the smell of cold

tap water made me prematurly bald and my gf dumped me

i hate tap water

this is simp[e science

But water freezes faster if it was boiled.

How can this be?

>>15160144
this not true dont shit up my thread please

>>15154465
temperature isn't a perfect reflection of the energy stored in a molecule. when you heat water up there's a lot of other quantum phenomenon that take place by adding energy to the system that can't be readily expressed as heat, but are slower to dissipate than strict temperature.

https://en.wikipedia.org/wiki/Thermal_conductivity
https://physics.info/planck/

what's happening is that the energy stored in a molecule actually has to cross an energy threshold before it starts dissipating (coming to equilibrium with it's surroundings) via thermal conductivity. so even though two materials may register as the same 'temperature', one might be at a higher energy state, which means it takes less input energy for it to start shedding it's excess energy as heat.

really it just 'boils' down to the idea that temperature is kind of shitty way of measuring the energy in matter, even though on the macro scale (for cooking and shit) these differences at the quantum scale make 0 difference.

Whaters for fags all I drink is big red ice cold fresh from the can
Uhhhhj blah blah blah it boils because of isotopic redaction with the positive temperature flux bitch shut the fuck up and get some pussy

Similar to the soup cylinder theory. The hot cylinders end up evenly distributed even afer the water has been cooled. So when you reboi it, it gets hot faster because of this. less cold cylinders and more even hot cyllinders

>>15160144
>But water freezes faster if it was boiled.

Water also boils faster if you freeze it first. Don't thaw it, though, that's unsafe--just pop those cubes right into the pot.

>>15154501
imagine being this retarded

>>15158175
Then why do I pay more for warm water than cold water on my water bill? Check mate atheists.

>>15154684
it might not be the water, it might be what the hot water is melting to add cancerous shit to your water intake, i.e. plastics

There is some structure to water due to hydrogen-oxygen bonds. Water molecules actually form globules. There are also minerals and ions, which form some bonds.

It takes energy to break those globules and H-H bonds.
I am not 100% sure why it takes less energy for second boil. I'll take a wild guess. With every 10 Celsius increase in temperature, the chemical reaction speed gets 2 to 4 times faster. When you boil the water the first time, you introduce extra oxygen into the water and this oxygen reacts to various ions and minerals. Some of these compounds are water insoluble (limescale as we know is one of them) and thus DO NOT form bonds with hydrogen atoms. Thus lowering the energy needed to bring the water to a boil. You can blow into a glass of cold and hot water with a straw. In hotter water there will be more white sediment than in the cold one.

By hydrogen bonds i dont mean chemical bonds as in H-O-H but H-O-H - - O -H2. Since the oxygen is very electronegative and hydrogen(proton) extremely electropositive, they attract and form these electrostatic bonds. This means water is POLAR. For an example fats are not polar and do not possess these properties.

>>15154554
>H20

>>15162446
h20 is water, dummy

>>15162923
H20 is not something that exists. Water is H2O.

>>15160443
yeah it is true what are you talking about?
i did extensive tests!!

>>15163358
i do not see the difference

are you a hard water shill?

>>15164756
Here is a quick chemistry nomenclature lesson:
H20 means 20 hydrogens, because 20 is after H. This doesn't exist.
H2O means 2 hydrogens and one oxygen (water).

>>15154465
dissolved things are more loosely held (salts) and some are removed(gasses) entirely after boilimg

>>15164797
we're talking about water. hydrogen is what they make bombs out of

The water is fully cooked and you're just reheating it the second time.

>>15154465
Chemistry PhD here

I'm not sure if your measurements are correct, but if they are a hypothetical mechanism could be that the first boil drives off the dissolved gases in the water. When water has impurities in it, the boiling point is elevated, so when those impurities are boiled off it reaches its (now lower) boiling point faster than it would otherwise

>>15165163
I can tell you're a PhD because it's clearly been a while since you've actually done calculations with equations. Impurities would only raise the boiling point of water by tenths of a degree Celsius—if that. Not anywhere close to enough to measure it by eye. And that is assuming that this water is more impure than the dirtiest water in Mexico.
>t. Chemistry Minor

>>15165198
>tenths of a degree Celsius
Presumably OP is American, so that could be ~1 degree F which would be perceptible on a common digital or even alcohol/mercury thermometer

>>15165219
Unless OP is boiling large vats of water, water would take only a few more seconds to get 1 degree F higher. Basically an imperceptible amount.

>>15165163
Came here to say this. The first boil removes air and dissolved gasses. It's the same purpose that a de-aerator has in a steam plant.

Pure water has a latent heat of vaporization of 970.3 BTUs per pound. If OP is getting his water to boil faster the second time, then something improved the heat transfer. Removing gasses would help. Potentially some other kind of conductive solid was introduced which would improve heat transfer as well.

because it is already used to boiling so it knows how to do it faster second time, I thought that's obvious
