Brain Teasers for Week-2

In an aquarium filled with water, a block of ice block floats, with a bar of gold frozen in it. We mark the current water level. When the ice has molten completely and the bar of gold has sunk to the bottom of the aquarium, will the water level be higher, lower, or still the same?
