1 answer

Sound would travel fastest in a solid medium because the particles are packed tightly in a solid and are able to transmit the sound waves without much resistance or distortion. In liquids and gases, the particles are more spread out and have more room to move around, which can slow down the transmission of sound waves. In a vacuum, there are no particles to transmit sound waves, so sound cannot travel at all.
