Ice cubes displace water (Making it rise)
Also: ice cubes take up more volume than liquid water.
if the cubes were completely underwater the whole time the level would stay the same once they melted. But because the top of the ice cubes are sticking out above the surface the water level will rise slightly.
Stays the same. Once it melts, it's density increases from it's frozen form.
The volume of ice above the surface is equivalent to the increase in volume due to ice's unique density v temperature curve.

Holy shit every one in this thread is dumb. notice how the ice floats ontop of the water level meaning when it melts the water level will rise as new water is added from the melting. is eveyone in her under 12 holy shit
It's because of the way they crystallize in a standard air cooling process.
In a perfect cooling process, where there is no space between crystallization, the ice is the same size.
It decreases because water's volume increases when it solidifies. If you fill a plastic bottle with water to the top and close it, it'll still warp when you freeze it, it's not air.
Just because you where right in the wrong way
But the icecubes aren't completely submerged into the water. Sure, water expands when it reaches a solid state, but it doesn't double it size. It expands roughly 9-10%, so unless the ice cubes were submerged 91-92% in the picture, the water levels would rise slightly.
When water freezes it's in an expanded form, if it were to melt the water level will go down.
Accounting for water displacement, water has more mass when it is frozen than it does when it is a liquid. A majority of the mass is lost when the ice cubes melt and the water level will be lower.
Some of the ice will float above the water level, but you dont know the volume of it and ice is less dense then liquid water which would make the water level lower. Simply there is no way of knowing the answer to this question.
Ice cubes displace equal to the volume of water they will melt into if they're floating. If any ice cube is totally submerged under the weight of other cubes or up against the glass, however, it's a different story.
While it is true that ice takes up more volume, it's also true the ice floats atop on the water.
However, I dont care enough to know if it will be higher, lower or the same level of the water.

The reason being that the each block of ice Will displace the same mass of water as what that block weighs (a 50gram ice block will raise the water as if 50grams of water was added to the glass)
This means the water will stay the same level.
Only reason the seawater rises when the icecaps melt is because a lot of that hunk of ice is above sea level AND supported by land beneath, propping it in to the air
Ice displaces water according to its weight, which doesn't change when it melts. When it melts, it "displaces" water according to its volume. So this would depend on how much ice there is, and how big the glass is.
As a smart person I must ask is the temperature of the water at the same temperature before and after? If that's the case then the water will not rise. If the temperature is getting hotter then the water will rise as it becomes less dense.
Floating ice takes up the same volume of water that it displaces. This thread is dildos.
>one electron of water
>one water of frozen electron
As you can see, the amount of water displaced is equal to the amount of water the ice will melt into.
Therefore the water level will stay the same. It's almost immediate when you do the math - that kinda surprised me. The formula for the volume of displaced ice was unnecessary
> given volume of liquid water at room temperature will increase in volume by about 9.05% after freezing
Anything that says otherwise is baiting. Water solidifies in a structure that makes it take up moar volume than liquid water.
Yes, but it turns out that 9.05% of the ice is sticking out of the water. That is what this >>593472029
shows. The ice is displacing water before it melts. When it melts, the water level would indeed fall WERE IT NOT for the fact that some of the ice was not in the water. It's simple math once you can unerstand the physics.
I feel kinda sorry for you... here.
stays the same, yes ice is less dense than water but the mass of it is the same, it's just there are more air molecules in the ice, so it floats slightly to counteract the lower density.
tl;dr the ice will decrease in volume by the exact amount of ice that is above the surface (providing the ice is perfectly still)
so it will stay the same
>mfw so many retards in this fucking thread
no, that's what happens, as long as ice is free floating, the ice will displace water mass equal to its own mass, however dense it is, provided it is water (which is hydraulic)
The volume of displacement is directly related to the weight of the ice, therefore the volume displaced decreases at exactly the same rate the ice melts and has nothing to do with the expansion due to hydrogen bonds (and other stupid chemistry shit).
The interesting point would be if the ice cubes float at exactly the mid-height point. If they floated lower than that then the minuscule difference in gravitation acceleration towards the Earth would cause the ice to be pulled down less, as more mass would be at the top meaning less pull as it's further away.
Of course you'd have to compare this TINY effect to the effect of the air current flowing over something lumpy compared to the relatively smooth surface of pure water. I think that would cause a bigger issue.
didn't read through thread but
>if you fill the cup while ice cubes are in, doesn't change
>if you add them after, however much the ice made it rise will stay at that level
>tl'dr stays the same fucking level
oh my god you're all so stupid
>ice is less dense than water
>therefore floats when it displaces enough water to support its weight
>as ice melts its mass decreases so needs to displace less water to stay afloat, but there is more water in the glass
>water level says the same
Nice bait faggot the mass of the ice is already displacing the water
Because the ice on land melts and goes into the sea, along with all the other water that falls as rain.
Density of water is inversely proportional to its temperature
The ice cools the water, increasing its density
Some may say its negligible, but fuck them
The water level will go down.. an incredibly small amount
The water would not rise, because water expands when it freezes. Try putting a full bottle of water in the freezer, notice how the ice is magically at the top of the bottle?
Same principle to why roads get some of their cracks when not built properly, water seeps in and doesn't drain out the baserock, stays there, freezes, and cracks.
Everyone who said the level goes the same/drops is on the right idea.
basically all water that falls as rain has been evaporated from the ocean at one point and eventually flows back into it, only to be evaporated again.
Rain has nothing to do with it
Water level would rise slightly due to the ice floating with some portion above the water line. As it melts the portion above the water line adds its volume to the water as well, and the water level would rise.
Of course, the water level could also rise because the temperature of the water would overall be warmer once the ice had melted, and warm water takes up more volume than cold water.
