Asked by bnat
A student views a table of the speed of sound waves in three different materials.
Material
Speed
(meters/second)
Density
(kg/m3)
air 330 1.20
water 1,500 1000
glass 5,100 2,500
Which conclusion can be drawn based on the information in the table?
A.
Sound travels faster in glass because it has a lower density than the other materials.
B.
Sound travels faster in glass because it has a higher density than the other materials.
C.
Sound travels slower in water because it has a lower density than the other materials.
D.
Sound travels slower in air because it has a higher density than the other materials.

The correct conclusion based on the information in the table is:
**B. Sound travels faster in glass because it has a higher density than the other materials.**
This conclusion may seem counterintuitive, but generally, the speed of sound in solids (like glass) is higher than in liquids (like water) and gases (like air). Although glass has a higher density than air and water, it also has a greater stiffness (bulk modulus), which contributes to the faster propagation of sound waves.
