Question

Order the speed of sound through these materials from the slowest to the fastest.

Answer 1

Answer:

1 ) Warm air

2) Cold air

3) Cold water

4) Steel

5) Hot molten

Explanation:

In order to solve this problem, we have to warn that the sound propagates more easily in denser media, in this way we have to identify the densities of the different materials.

Density cold air = 1.2 [kg/m^3]

Density warm air = 1.01 [kg/m^3]

Density cold water = 1000 [kg/m^3]

Density steel = 7500 [kg/m^3]

Density hot molten = 14100 [kg/m^3]

Therefore in order from the slowest to the fastest:

1 ) Warm air

2) Cold air

3) Cold water

4) Steel

5) Hot molten

Answer 2

Answer:

speed of sound in cold air

speed of sound in warm air

speed of sound in water

speed of sound in hot molten lead

speed of sound in steel
