Question

Q. 8. A piece of ice is placed gently on the surface of water in a glass so that when the ice floats, the
water comes up to the brim of the glass. What will happen to the level of water when the in
melts? Will it overflow?
Ans. In accordance with the Anchimedes' principle, when the ice melts, the volume of water so formed i
be equal to the volume of the displaced water. So, the level of water in the glass will remain unaffected.
Q.9. In the previous question, what will happen if instead of water the glass is filled with
(s) a liquid denser than water.
(b) a liquid lighter than water.​

Answer 1

Answer:

piece of ice is placed gently on the surface of water in a glass so that when the ice floats, the water conies up to the brim of the glass. ... Answer: In accordance with the Archimedes' principle, when the ice melts, the volume of water so formed will be equal to the volume of the displaced water.

When the liquid denser than water is filled in the glass, then the volume of water formed by the melting of ice will be more than the volume of the liquid displaced, so the level of water will rise. Therefore, the water will overflow from the glass. ... So, the water will not overflow from the glass.
