Material Density (g/cm3)
Water
1.00
Steel 7.86
Aluminum 2.58
Polyethylene (plastic) 0.92
Through which material will sound travel the fastest?
steel
water
aluminum
polyethylene (plastic)

aluminum
Sound speed depends on the material's stiffness-to-density ratio (v ∝ √(elastic modulus / density)). Aluminum has a higher stiffness-to-density ratio than steel, water or polyethylene, so sound travels fastest through aluminum.
