What happens to the floating ice cubes after they are added to the water?

When ice cubes are added to water, they float because their density is less than that of liquid water. As they float, the ice begins to melt, causing a portion of the ice to convert into water. This process absorbs heat from the surrounding water, slightly lowering the temperature of the liquid. Ultimately, the melted ice contributes to the overall water volume, but the total water level remains unchanged due to the displacement caused by the floating ice.
