Question

5. On which property of the particles in
a material does the speed of sound
depend? sc.7.P.10.3
A the dimensions of the particles
B the forces between the particles
C the shape of the particles
D the number of particles

Answer 1

Answer:

B. the forces between the particles

Explanation:

The speed of sound is highly dependent on the "medium" that it is traveling through. The more rigid the medium is, the faster the sound travels. The density of a medium is dependent on the forces between the particles. When it comes to solids, their particles are tightly packed because they have a very strong intermolecular force. Their density is greater too, and due to lack of space, they are "not compressible." This allows the sound to travel faster as well.
