What Happens to Water Level When Ice Melts in a Beaker?

[Grimstone]

An ice cube has a higher volume than an equal mass of liquid water. But the amount of water that a floating ice cube displaces is the amount of its volume under the water surface. That turns out to be exactly equal to the volume of water that will be created when that ice cube melts.

So then the water level will not change in the least bit. assuming tht hte icecube flaots with as much as itself under the surface. (wich it will do).

There's nothing to disagree with. If anyone disagrees they don't understand the basic physics behind it.

Time for a simple science-fair-level experiment. Put water in a clear container, like a drinking glass, add ice, and use a sharpie to mark the water level. Come back later when some or all of the ice has melted, and check the water level vs the ink-mark. This would be a SLOW demonstration and would be a bit tedious. The best way to make this experiment fun for a science fair would be to use a web-cam to record the level as the ice melts, then speed up the loop on a laptop so people viewing the science-fair projects can see the process in its entirety.

Like I said, draw a diagram then it's obvious.

I think you can just go back and read the posts to see that everyone agrees with Doc Al. It was stated and restated many times.

What do you think and why?

i didn't went through the entire thread but i think that the floating piece of ice does puts some pressure on the surface of the water which may cause the surface of the water to rise when the ice cube melts the pressure is gone but the water level will not drop as the molten ice cube is converted to water itself so level of water not changes according to me i am not 100% sure if i am right so correction will be highly appreciated
