Water level will first rise up then it will go down

Detailed explanation-1: -When a floating piece of ice melts into water, it contracts by the volume equal to the volume of ice pieces above the water surface while floating on it. Hence, the level of water does not change when ice floating on it melts.
Detailed explanation-2: -according to the Archimedes principle, the floating substance displaces some liquid, so when the ice melts, there will be no change in the water level as the melted ice will occupy the same volume as it was occupying earlier.
Detailed explanation-3: -Since water ice floats, it helps life survive on Earth. In the winter, when surface temperatures are low enough for water to freeze, floating ice forms a layer of insulation on top of lakes and seas. This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive.
Detailed explanation-4: -When a piece of ice is placed in a beaker containing water, some of its portion remains out of the water level. Since the volume of ice is greater than the water hence after melting the volume of the piece will decrease and the water level will remain the same.
