Question
When a piece of ice floating in water melts, the level of water inside the glass remains same. Explain.
Solution
A piece of ice displaces an amount of water equal to its own weight. Volume of water displaced is equal to volume of submerged part of ice cube. When ice cube melts, its volume decreases and gets occupied in that volume of water which is displaced by it. As a result, level of water inside the glass remains same when piece of ice (ice cube) melts.
