Answer:
water would allow sound to travel the fastest due to its higher density and elasticity compared to air, which makes it a better medium for transmitting sound waves.
Explanation: Answer is in explanation
Sound travels fastest in solids, and specifically in materials that are elastic, dense, and have strong intermolecular forces between their particles. Among the options given, glass is a solid, but it is not very elastic or dense, so it is not the best material for sound to travel through quickly. Lead is a dense material, but it is also very heavy and not very elastic, so it is not the best either.
Air is a gas, and gases are not very dense or elastic, so sound travels relatively slowly through them. The speed of sound in air is about 343 meters per second at standard temperature and pressure.
Water is a liquid, but it is much denser and more elastic than air, so sound travels about four times faster in water than in air, at around 1,484 meters per second.
Therefore, among the given options, water would allow sound to travel the fastest due to its higher density and elasticity compared to air, which makes it a better medium for transmitting sound waves.
