A piece of ice, having a stone frozen in it, floats in a glass vessel filled with water. How will the level of water in the vessel change when the ice melts completely?
Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Understand the principle of buoyancy. When an object floats, it displaces a volume of liquid equal to the weight of the object.
Step 2: In this scenario, the piece of ice floats in the water. The ice, along with the stone inside it, displaces a certain volume of water, which corresponds to the total weight of the ice and the stone.
Step 3: When the ice melts, it turns into water. The volume of water produced by melting is equal to the volume of water that the ice was displacing when it was solid.
Step 4: Since the density of the water produced from the melted ice is the same as the density of the surrounding water, the overall water level will not change.
Conclusion: Therefore, the level will not change when the ice melts completely.
