ice is ALWAYS moving...

2.2 million google hits for:
antarctic ice all time high
take a look at a couple of the top articles
(BTW, could some tell me how seas can rise higher around Antarctica than the rest of the globe? Is there some gravitational anomaly that causes water to especially pile up there higher than in the rest of the oceans a bit further away.)
A secret room in a secret building with dim lights, a round table with seating filled with Liberals, dishes filled with snacking vegetables, and cups of tea, and this kinda crap is what they come up with.
Antarctic ice increased this year, as well. But that was based on actual satellite measurements and not computer modeling.
Seems to me I heard not long ago that there were complaints that the Jersey shore line was receding, salt marshes drying up, especially after storm Sandy - water there probably came from here.....
No.
All ya all are welcome.
Only if cup is filled all the way to the very brim.
The ice that extends above the water’s surface will overflow the cup upon melting.
The overall mass doesn’t change but liquid volume does.
Imagining a snack bar for some of these folks is..
Well
..
Let me get back to you, I don’t have a strategy, uhhh yet.
No.
ice is ALWAYS moving...
But more ice makes tge water rise...
And just as in the case of the island becoming “overloaded” in the event the U.S. might station more troops there, once the ice cube melts, the glass will tip over!.
Volume of cup = constant = occupied by liquid water + the one tenth of the ice cube on top of liquid level.
Ice cube melts and now total volume of liquid = original volume + volume of melted ice.
Additionally, temperature of total liquid rises to ambient temperature which expands liquid volume contained by constant volume of cup.
Hence, puddle.
No, but while the ice is in the water the water will be displaced and look higher in the glass. Record Ice in Antarctic is displacing the water around it making it appear higher. That's my story and I'm sticking to it.
It depends on the temperature of your room. While the thermal expansion of water is small, if the room is warm enough, the level of water in the glass will at first go down a little and then go up as the water temperature goes from 0 degrees C to room temp. It would also decrease a little due to evaporation.
Harder to figure than I first thought, but if the room is warm enough, it actually might overflow the cup.
Incorrect.
The amount of water displaced by the floating ice cube is exactly the same amount of water that is in the ice cube when it is melted. The ice cube is physically larger but the same weight because the water expands when frozen making its density lower and therefore part of floats above the water.
Ah, but if you go down that road the glass also expands with temperature so it will hold more water... I’d guess the expansion coefficient of glass is higher than water - but I don’t know (and I’m too lazy to look)...
But when the water temperature continues to rise to ambient, the water will expand further and overflow.
Liquid water is one compound that expands upon freezing as well as heating.
Let’s make some stipulations...
The water and the container the water is in are at room temperature before the ice cube is added.
The moment the ice cube is added to the water the water level goes to exactly the edge of the container (let’s not further complicate it with surface tension...).
As the ice cube melts the water in the glass is going to shrink (until the water reaches 4 C if it were to get that cold, if it gets colder it will expand again). So as the ice melts the water will be slightly lower than at the moment it first started to melt because the water is being cooled by the ice relative to room temperature it started at. When the ice cube is fully melted and the water returns to room temperature the water level will return to exactly the edge of the container if it was exactly at the edge the moment the ice cube was first put in the water.
If you want to take it further than that, then you have to figure out the temperature coefficient of the container and how much it changes with temperature, because it will by some degree.
No; why?
