Concept:
- A floating object displaces an amount of water equal to its own weight.
- Since water expands when it freezes, one unit (of weight) of frozen water has a larger volume than one unit of liquid water.
Explanation:
- As the density of oil water and ice is as follows:
dice = 0.91 g/cm3, d water = 1 g/cm3, doil is = 0.85 g/cm3
- If the ice is dropped in oil, as the density of ice is more it will sink in the oil in the container.
- Now when the ice melts it gets converted into water, but as the water density is also more than oil, so the water will also sink and as a result, the level of oil will rise.
So here, overall level of the oil will rise.
Note: According to the official answer key option B is correct.

Understanding the Scenario
When a piece of ice is dropped into a vessel containing kerosene oil, we need to analyze what happens when the ice melts. Ice is less dense than water, and when it melts, it converts into water, which is denser than both ice and kerosene oil.
Ice in Kerosene Oil
- Ice floats on kerosene oil because it is less dense than kerosene.
- When the ice is submerged, it displaces a volume of kerosene oil equal to the weight of the ice.
Melting Process
- As the ice melts, it turns into liquid water.
- The volume of water produced from the melted ice will be less than the volume of kerosene oil displaced when the ice was floating.
Effect on Kerosene Oil Level
- Since the volume of the water formed from the melted ice is less than the volume of kerosene oil that was displaced by the floating ice, the overall volume of kerosene oil displaced decreases.
- Therefore, as the ice melts, the kerosene oil level rises.
Conclusion
- The correct answer is option 'A': The level of kerosene oil will rise when the ice melts.
This phenomenon can be attributed to the differences in density between ice, water, and kerosene oil, illustrating important principles of buoyancy and displacement.
