Question

How does speed of sound change when we go from
solid to gaseous state?

Answer 1

Answer:

Decreases.

When we move from solid state to gaseous state, the speed of sound decreases generally.

Hence, the correct answer to your question will be decreases.

Change = Decrement

Hence, there is a decrement in the speed of sound.

This is why, you hear the sound of a upcoming train earlier than usual if you hear it's sound through the railway tracks.

Answer 2

Answer:its because of molecules

Explanation: the vibration between the closely packed molecules in a solid help in transferring the sound easily while in gases the molecules are away from each other so it will take time for the sound to travel
