Question

why speed of sound is more in Al than iron​

Answer 1

Answer:

The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior. ... For example, while sound travels at 343 m/s in air, it travels at 1,481 m/s in water (almost 4.3 times faster) and at 5,120 m/s in iron (almost 15 times faster).
