Detailed Solution

The above statement is False.
A sound is basically a sequence which can propagate through a compressible medium like water or air, or any solids. As molecules in the liquids are close to each other but lesser than solids, this allows sound waves to travel rapidly inside water also. This allows the student to hear the sound clearly even if he rings the bell inside of the water.
The correct statement would be the student is able to hear the sound clearly when a student holding a bell in one hand and dipping it into the water and keeping one ear on the surface of the water rings the bell inside the water.
