Which of the following statements describe the speed of sound? Select all that apply.

The speed of sound is faster in aluminum than in water.

The speed of sound is slower in air at 20 C than in air at 0 C

Sound moves faster in most solids than in gasses.

Sound moves faster in air than in water.

The speed of sound is slightly faster in the summer than in the winter.

Respuesta :

1, 3, and 5 are correct.

Answer:

The speed of sound is faster in aluminum than in water.  

Sound moves faster in most solids than in gasses.

The speed of sound is slightly faster in the summer than in the winter.

Explanation:

As we know that the speed of sound is given by the formula

[tex]v = \sqrt{\frac{Y}{\rho}}[/tex] (in solids)

[tex]v = \sqrt{\frac{B}{\rho}} = \sqrt{\frac{\gamma RT}{M}}[/tex] (in gases)

So here from above formulas we can say that elasticity of solids is more than the elasticity of liquids or gases

so here we have

1). The speed of sound is faster in aluminum than in water.  

3). Sound moves faster in most solids than in gasses.

Also as we can see that the speed of sound is directly depends on the temperature of the medium or gas

so here as we increase the temperature the speed of the sound in that medium will increase

so here we have

5). The speed of sound is slightly faster in the summer than in the winter.
