Question 158

The speed of sound is different in different states of matter.

The speed of sound in liquid ethanol is approximately 1200 m/s.

Which of the following correctly compares the speed of sound in solid ethanol and gaseous ethanol with the speed of sound in liquid ethanol?

A

Solid ethanol: less than 1200 m/s1200\text{ m/s}1200 m/s; Gaseous ethanol: less than 1200 m/s1200\text{ m/s}1200 m/s

B

Solid ethanol: less than 1200 m/s1200\text{ m/s}1200 m/s; Gaseous ethanol: more than 1200 m/s1200\text{ m/s}1200 m/s

C

Solid ethanol: more than 1200 m/s1200\text{ m/s}1200 m/s; Gaseous ethanol: less than 1200 m/s1200\text{ m/s}1200 m/s

D

Solid ethanol: more than 1200 m/s1200\text{ m/s}1200 m/s; Gaseous ethanol: more than 1200 m/s1200\text{ m/s}1200 m/s
