A piece of ice is floating in water kept in a beaker. When all the ice melts the level of water will - (1) first rise and then fall (2) fall (3) remain the same (4) rise

Description : A piece of ice is floating in water kept in a beaker. When all the ice melts the level of water will - (1) first rise and then fall (2) fall (3) remain the same (4) rise

Last Answer : (3) remain the same Explanation: The submerged portion of the ice on melting shrinks a little in volume. So the level of water goes down a little. But this is just made up by the water added by the melting of upper portion.
