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
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.
