Question

An ice block having two similar metallic pieces is floating in water in a vessel as shown in figure. After sometime the ice melts completely then

• A. the water level rises in the vessel
• B. the water level falls in the vessel
• C. the water level does not change in vessel
• D. the water level may rise or fall depending upon the ratio of masses of ice and metallic pieces.

Answer 1

Answer: (A)

the water level rises in the vessel

An ice block having two similar metallic pics floating in water in a vessel.

The water level rises in the vessel because the reason is floatation and density of the ice and water relativity. The ice cube with ball floats. In this case, an additional volume of water displaced due to the weight of the metal piece weighs the same as the weight of the ball. This is more than the volume of a ball which has a higher density than water before completing the melting of ice, the ball embedded in ice sinks in the water, temporary the level of water will rise.
