if I have a pool that is 20x20 surface area and I put a 200 gallon block of ice it, the water level will go up by X amount. when it melts how much will the water level change?

That is correct, although it is an interesting exercise to calculate how much the sea level would rise ifphilip porhammer said:NICE! that's what I thought! only Ice that is grounded will effect the sea level. thanks

Well, not quite. Much of the floating sea ice is fresh water ice. Sea water is denser than fresh water. Ergo, the volume of fresh water produced by the melting ice will be a slight bit larger than the volume of sea water that it displaced. It's a small effect, but an effect none the less.philip porhammer said:NICE! that's what I thought! only Ice that is grounded will effect the sea level. thanks

True. I was thinking of mentioning that, but decided it would just confound the central question.Janus said:Well, not quite. Much of the floating sea ice is fresh water ice.

That's true if it is fresh water ice floating in fresh water. But fresh water ice floating in salt water is a different case because salt water is denser than fresh water. ( one way to look at it is that the fresh water iceberg floats a bit higher in salt water than it does in fresh water, so a little less than 90% of it will be underwater, but it still produces the same volume of water when it melts.Kevin the Crackpot said:I would have thought that the water level won't change at all.
Ice is less dense than water (very few substances are less dense as a solid rather than a liquid). That's why an iceberg only shows ten percent or so above water, and the other 90% is under water.
When the ice melts, the water perfectly occupies the 90% under water that was originally occupied by the iceberg, so no change in water level.
This is from the page referenced below:Nugatory said:That is correct, although it is an interesting exercise to calculate how much the sea level would rise if
A) all the Greenland ice cap were to completely melt
B) all the Antarctic ice cap were to completely melt
A lot. It is interesting to note that in the region of Central American, there are caves under water greater than 60 meters where bones, including human bones have been found. This is the effect of the various ice ages reducing the sea level. It should hold that if all of the current ice were to vanish, the sea levels would rise, and dramatically.If the Greenland Ice Sheet melted, scientists estimate that sea level would rise about 6 meters (20 feet). If the Antarctic Ice Sheet melted, sea level would rise by about 60 meters (200 feet).

As the ice melts, the water level in the pool will increase. This is because the ice takes up more space in its solid form than it does in its liquid form. So as it melts, it will take up less space and cause the water level to rise.
Yes, the water level will continue to rise as long as there is still ice melting in the pool. Once all the ice has melted, the water level will stabilize.
The amount of ice needed to cause a noticeable change in the water level will depend on the size of the pool. Generally, the larger the pool, the more ice will be needed to see a significant change in the water level.
No, the water level will not decrease once the ice has melted completely. The water level may decrease slightly due to evaporation, but it will not decrease significantly.
The time it takes for the ice to melt and the water level to stabilize will depend on several factors such as the temperature of the pool, the amount of ice, and the size of the pool. Generally, it can take a few hours to a day for the ice to melt completely and for the water level to stabilize.
