Question

sound through different materials
sound waves require a medium through
which to travel, and the properties of the
medium affect the way sound travels
through it. materials that are easily
compressed transmit waves more slowly
than materials that are hard to compress.

1. which material shown in the table would

you expect to have the lowest average
speed of sound, based on the data?
explain.
type your answer here.

material | phase (at 20 °c)
--- | ---
air | gas
water | liquid
cement | solid

Explanation:

Gases are far easier to compress than liquids and solids. The given rule states that easily compressed materials transmit sound waves more slowly. Air is the only gas in the provided table, so it will have the lowest average speed of sound.

Answer:

Air will have the lowest average speed of sound. Gases like air are much easier to compress than liquids (water) or solids (cement), and materials that are easily compressed transmit sound waves more slowly, according to the provided information.
