The aluminum allows the sound wave to travel faster than air at 68 degrees because the molecules in aluminum are closer together.

• This statement is true because solids are more dense than gases. Mechanical waves require a medium. The closer the molecules are, the quicker they can transfer the sound wave.

• This statement is true because solids are less dense than gases. Mechanical waves require a medium. The closer the molecules are, the quicker they can transfer the sound wave.

• This statement is true because solids are more dense than gases. Mechanical waves do NOT require a medium. The closer the molecules are, the quicker they can transfer the sound wave.

• This statement is true because solids are more dense than gases. Mechanical waves do NOT require a medium. The farther apart the molecules are, the quicker they can transfer the sound wave.
