Question

A piece of Ice was tied with a string to a water bucket’s bottom, and the water bucket was filled with water with ice fully submerged in it. What would be the impact on the level of water when the ice melts away completely?
A. The level of water will go up
B. The level of water will go down
C. The level of water will remain unchanged
D. The level of water will first increase then come to the previous on

Answer 1

The correct answer is option B. The level of water will go down.

When ice floats in water, the level of water remains unchanged on melting because it replaces equal weight of water as the weight of ice.

When ice is taken at the bottom of the bucket, and is melted at the bucket's bottom, then ice replaces the volume of water equal to its volume. Density of  ice is less than that of water. Therefore, the water level goes down.
