Question

An ice cube floats in glass of water. As ice melts, how does the level of water in glass change? Would it make any difference if the ice cube were hollow? Explain.

Answer 1

ice cube floats on water because it's density is less than water. when the ice cube melts it turns into water (solid-liquid) due to which the water from ice get added in water as a result level of water in glass increases.if the cube is hollow than also the level of water will increase but the level will be less of hollow cube than complete cube as in hollow cube the proportion of ice will less.
hence, the difference in level of water will less when use hollow ice cube.

Hope it helps mark me as brainliest.
