Why do mechanical waves travel fastest through solids?
The particles are closer together so energy is transferred faster
The particles are farther apart so energy is transferred faster

Sound waves can travel through all three states of matter. Which of the following best explains why sound travels most quickly through a solid?
Solids always produce an echo, which makes the sound seem louder to the human ear.
Only solids allow the vibrations to travel from one atom (particle) to another.
In solids, the atoms (particles) are closest together, which allows the vibrations to travel rapidly from one to another through the object.
Sound does not travel quickly through a solid. It travels most rapidly through a gas.
Why can't sound travel through outer space?
There is almost no matter in outer space, so the vibrations have no way to travel through the atmosphere. There is nothing to carry the sound waves through space.
Sound actually travels very quickly through outer space because there is no matter to slow down the sound waves.
There are too many planets and stars in outer space that absorb all of the sound waves, so they cannot travel to the human ear.
Because outer space is a "vacuum," the vibrations are irregular and travel in too many directions for us to detect the sound.
