Given below are two statements: one is labelled as Assertion \(A\) and the other is labelled as Reason R
Assertion A: A sound wave has higher speed in solids than gases.
Reason R: Gases have higher value of Bulk modulus than solids.
In the light of the above statements, choose the correct answer from the options given below.
[JEE Main 2025, 28 Jan (Shift 1)]
✓ Correct answer: a)
A is true but R is false.
Explanation
Elasticity of solids is more than gases.
\(B=\left(\frac{\Delta P}{\Delta V}\right)V\)
For a given change in pressure change in volume of solid is small hence solids have higher bulk modulus.
