Description : When a cube of ice floating on water in a beaker melts, the level of water in the beaker (a) rises (b) falls (c) remains the same (d) first rises and then falls
Description : If ice floating on water in a vessel melts, the water level in the vessel - (1) increases (2) does not change (3) first increases before decreasing (4) decreases
Last Answer : (2) does not change Explanation: When ice floating on water in a vessel melts, the water level in the vessel does not change. This is because when floating, the ice displaces an amount of water ... that the mass of the liquid displaced by a floating object is equivalent to the mass of the object.
