Why Sound Travels Faster in Solid?

Answer: Sound travels faster in solids because the particles in solids are closely packed, leading to a higher elasticity and greater intermolecular forces, facilitating the transmission of mechanical waves at a quicker pace compared to liquids and gases.

The speed of sound in a material is determined by its density, elasticity, and the intermolecular forces between its particles. In solids, such as metals, the particles are closely packed, allowing for faster transmission of mechanical waves. The strong intermolecular forces and higher elasticity in solids contribute to the efficient transfer of sound energy, resulting in a faster speed of sound compared to liquids and gases where particles are more loosely arranged. The arrangement and interactions of particles in solids create a medium through which sound waves can propagate more rapidly, making sound travel faster in solid materials.
