Question

Statement-I: Velocity of sound in solids is generally greater than that in gases. Statement-II: Bulk modulus of a gas is greater than that of solids.

G1 Physics · Accepted Answer

Sound speed depends on elasticity and density. The elastic modulus of solids is generally much larger, so sound is typically faster in solids. The statement that gas bulk modulus is greater than that of solids is incorrect.
