A student questioned how the properties of different materials affect the speed of sound waves traveling through them. The student found the following data in a chemistry handbook for the speed of sound in gases, liquids, and solids. The student analyzed the data to make predictions about the speed of sound on materials with various densities and states of matter. Which TWO predictions can be made based on the data shown in the table?

• The speed of sound generally increases as it moves from gases to liquids to solids.

• The speed of sound generally increases as it moves from liquids to gases to solids.

• The speed of sound generally increases as it moves from solids to gases to liquids.

• As the density of liquids and solids increases, the speed of sound generally increases.

• As the density of solids and gases increases, the speed of sound generally decreases.

Answer explanation

The correct answers are choice (A) The speed of sound

generally increases as it moves from gases to liquids to

solids, and choice (E) As the density of solids and gases

increases, the speed of sound generally decreases.

Choice (B) is incorrect because the general trend is

increasing speed from gases to liquids. Choice (C) is

incorrect because the speed of sound generally increases

as it moves from gases to liquids to solids, not solids

to gases to liquids. Choice (D) is incorrect because this

statement is true of liquids, but not solids.
