Question

The volocity of sound is minimum in :
A ) N2
B) CO2
C) Air
D) H2​

Answer 1

Answer:

Carbon dioxide

Explanation:

Carbon dioxide is more dense than air ( at the same temperature and pressure ), because the individual particles are on average more massive, not because they are close together. They move very slowly for a given kinetic energy. Hence the velocity of sound is minimum in carbon dioxide.
