Question

through which gas in the table will sound waves travel faster than they would travel through ammonia?

a. nitrous oxide
b. argon
c. methane
d. air

Explanation:

Step1: Compare the speed of sound in each gas with that in ammonia

The speed of sound in ammonia is \(415\) m/s.

• For nitrous oxide: \(263<415\)
• For argon: \(323<415\)
• For methane: \(450 > 415\)
• For air: \(346<415\)

Answer:

C. Methane
