Statement I: The speed of sound in solids is maximum though their density is larger than liquid. Statement II: The coefficient of elasticity of solid is large.

Question

Statement I: The speed of sound in solids is maximum though their density is larger than liquid. Statement II: The coefficient of elasticity of solid is large. (A) If both Statement I and Statement II are true and the Statement II is correct explanation of the Statement I (B) If both Statement I and Statement II are true but the Statement II is not the correct explanation of the Statement II (C) If Statement I is true but Statement II is false (D) If both the Statements are false

The velocity of sound in solid is given by, v=√E / ρ. Though ρ is large for solids, but their coefficient of elasticity E is much larger (compared to that of liquids and gases). That is why v is maximum in case of solid.

Q. Statement I: The speed of sound in solids is maximum though their density is larger than liquid.
Statement II: The coefficient of elasticity of solid is large.

If both Statement I and Statement II are true and the Statement II is correct explanation of the Statement I

If both Statement I and Statement II are true but the Statement II is not the correct explanation of the Statement II

If Statement I is true but Statement II is false

If both the Statements are false

The velocity of sound in solid is given by, $v = E / ρ$ . Though $ρ$ is large for solids, but their coefficient of elasticity $E$ is much larger (compared to that of liquids and gases). That is why $v$ is maximum in case of solid.
