A piece of ice floats in a vessel with water. Kerosene is poured over the water so that the piece of ice is completely covered with kerosene. Will the water level in the vessel change if the ice melts? If it changes, how?

Will decrease. Yes, it will change, since the volume occupied by the same mass of water in the form of ice is greater than in the form of water. Since the density increases during melting, the volume occupied decreases and the liquid level decreases. And the piece of ice itself is already a certain part of the liquid in the vessel, the same principle of Archmed’s law.
