Question

An empty vessel produces louder sound than a filled one because.

• A. The liquid in the filled vessel absorbs the vibrations of the liquid molecules
• B. The air molecules in empty vessel have greater amplitude and hence greater intensity than liquid molecules in the filled vessel
• C. The density of air is less than the density of liquid contained in the vessel when filled
• D. The kinetic energy of particles constituting the air column is greater as compared to the kinetic energy of particles of liquid column

Answer 1

The correct option is B The air molecules in empty vessel have greater amplitude and hence greater intensity than liquid molecules in the filled vessel

An empty vessel produces louder sound than a filled one because the air molecules in empty vessel have greater amplitude and hence greater intensity than liquid molecules in the filled vessel
