Question

If a piece of ice floating on the surface of water in a beaker melts completely, the level of water

• A. Rises
• B. Remains the same
• C. Falls
• D. Initially rises and then falls

Answer 1

The correct option is B

Remains the same

Archimedes' principle: It states that the loss in weight of a body in the liquid will be equal to the weight of the liquid displaced by immersed part of the body.

1. Here, when the ice starts melting, the loss in weight of the ice in the beaker is equal to the weight displaced by the immersed part of the ice.
2. Hence, there will be no change in the water level.

Explanation for the correct option:

Option B:

1. According to Archimedes' principle, the water level will remain the same.
2. Hence, this option is the correct option.

Explanation for the incorrect options:

Option A:

1. According to Archimedes' principle, the water level will remain the same.
2. Hence, this option is not the correct option.

Option C:

1. According to Archimedes' principle, the water level will remain the same.
2. Hence, this option is not the correct option.

Option D:

1. According to Archimedes' principle, the water level will remain the same.
2. Hence, this option is not the correct option.

Hence, option B is the correct option.
