Question

Denser materials have more tightly packed particles so the vibrations of the particles are transmitted faster, thus sound moves faster through denser materials

True or False?

Answer 1

True, particles in sound move faster in denser objects.

Answer 2

True

Step-by-step explanation:

Since sound is more easily transmitted between close molecules, it travels faster in the denser substance. Sound moves faster through denser air because the molecules are closer together in dense air and sound can be more easily passed on.
