Question

what changes occur in the speed of sound when it travels from iron to air​

Answer 1

Answer:

Speed decreases.

Explanation:

Speed of sound in different states of matter is as follows:

Speed in solid > Speed in Liquid > Speed in Gas

So when the sound travels from iron(solid) to air(gas), its speed decreases.

Answer 2

The speed of sound decreases when it travels from iron to air​ .

- Generally, the speed of sound is faster in metals.

- Actually, the speed of sound in iron is about 5130 m/s.

- As we know, the speed of sound in air is about 343 m/s.

- This means sound travels 14 times faster in iron than air.

- So, when the sound waves travel from iron to air, the speed decreases considerably.
