In which medium does sound travel faster and why
Sound travels faster in solids because molecules in a solid medium are much closer together than those in a liquid or gas, which makes the sound travel faster. Sound waves travel over 17 times faster through steel than air.
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
