Question

speed of sound in carbon dioxide is less than that in air​

Answer 1

Answer:

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.

Answer 2

The speed of sound in carbon dioxide will be lesser than in air.

• The substance through which sound travels is called the medium, and sound moves best through air and water.
• The speed of sound is influenced by several factors, including medium, density and temperature.
• When the medium is dense, the molecules in the medium are closely packed, which means that the sound travels faster.
• The more mass the molecule lesser will be it's kinetic energy.

• carbon dioxide molecule is massive than air molecules.  
• Hence the speed of sound in carbon dioxide will be lesser than in air.
