when a chunk of floating ice melts will the water level go up or down?

Question

like one large chunk of ice floating in a tub of water ,will the water level be higher or lower when the ice melts?

Answer 1

higher.

Answer 2

If it is truly floating (unlike parts of the polar ice caps) , the level will not change. Even though some of the ice is above the water to start, it is still displacing it's own mass of water, and when it melts into the denser liquid state it will take up exactly the space in the water as it displaced as ice. As the water warms after the ice melts, the level will rise as the water expands from heat, but it will be hard to measure in a small tub

Answer 3

Assuming the ice was buoyant enough that part of it was not already displacing the water in the tub, or was "sticking out," the water level would rise.

The water level may not necessarily rise to the same level as if all of the chunk of ice were submerged because ice and liquid water have different densities (this is the reason ice floats) and a mass of ice will be slightly larger in volume than the same mass of water.

If we are talking about something small, like an ice cube from your freezer, the water level would only go up a small amount.

Answer 4

Well one would think it would be about the same. The ice is displacing the water with its volume. As it melts the displacement by the ice is lessened and filled with the melt water.

Now in the case of the polar ice caps, it is thought that the melting caps are making the oceans rise. But that's a super large scale thing.

Answer 5

i think at first water level go up but more than 0 deg it will go down at 4 deg. it have a min. level beygi
