# when ice block is floating in water in vessel,then level of water in vessel remain same even after ice melt

Relevance

No.

The Ice block, when melted, will Increase the level in the vessel.

Ice blocks contain air trapped inside, so it is difficult to estimate exactly how much water will be added to the Vessel.

• If there is ice floating in water, and the ice melts, the water level remains the same. The ice displaces a volume of water equal to its weight. Because ice is less dense than water, some of the ice will be above the surface. The volume of ice below the surface is the volume of water displaced, and is equal to the total weight of the ice, which includes what's above the surface. When the ice melts, its density increases, and it produces a volume of liquid water that's the same as the volume of ice that was previously submerged.

• Assuming density is 1g/cc for water and there is no evaporation.

Ice floats because it is lighter then water. (water expands when below 4 degrees centigrade till it solidify).

It therefore displaces its own weight in water. So the level of water increases. When the ice melts, water remains but not exactly at that level but a little lower. Now it shrinks a bit. (Remember the 4 degrees above?.)

Resultant is there is an increase in water level.

This is as simple as I can explain without mathematical models.

• If your question is "why is this true?", then the reason is water has the same density in liquid and frozen form.
