Question

Statement-I : Velocity of sound in solids is more compared to that in gases.

Statement-II : Bulk modules of gas is more than that of solids.

(1) Statement I is correct statement- II is correct

(2) Statement I is correct statement II is incorrect

(3) Statement I is incorrect statement II is correct

(4) Statement I is incorrect statement II is incorrect

Answer 1

Correct option is : (2) Statement- I is correct statement- II is incorrect

Speed of sound in medium depends on elastic and inertia properly of medium.

for gas \(v = \sqrt{{}^B / {}_\rho}\)

for solids \(v = \sqrt{{}^Y / {}_\rho}\) 

The elastic properly of solids happens to be many fold greater than that of elastic properly of gases.

Bulk modulus of gas depends on the process,

\(B = \frac{-\Delta P}{\Delta V / V}\), which varies between 0 to \(\infty\) therefore in general statement 2 is incorrect.
