Answer 1

cannot be compared with its value in water.

If B is the bulk modulus and ρ is the density, then the velocity of sound is given by:

\[Velocity = \sqrt{\frac{B}{\rho}}\]

If both B and ρ are greater, then we cannot compare \[\frac{2B}{2\rho} = \frac{3B}{3\rho} = \frac{B}{\rho}\]

For proper comparison, we need numerical values.
