Question

Speed of sound in air is 332 m/s at NTP. What will be the speed of sound in hydrogen at NTP if the density of hydrogen at NTP is (1/16) that of air?

A. 664 m/s
B. 1328 m/s
C. 1155 m/s
D. 166 m/s

Answer 1

The speed of sound in hydrogen at NTP is 1328 m/s.

Step-by-step explanation:

To determine the speed of sound in hydrogen at NTP, we can use the relationship between the speed of sound and density. The speed of sound is inversely proportional to the square root of the density of the medium. Since the density of hydrogen at NTP is 1/16th that of air, the speed of sound in hydrogen would be 4 times greater than the speed of sound in air.

Given that the speed of sound in air at NTP is 332 m/s, the speed of sound in hydrogen at NTP would be:

332 m/s x 4 = 1328 m/s
