Question

If the density of a gas is increased 9 times , then the velocity of sound in that gas changes by what factor? ​

Answer 1

Answer:

The speed of sound depends on the medium and the state of the medium. In a fluid, because the absence of shear forces, sound waves are longitudinal. A solid can support both longitudinal and transverse sound waves. In air, the speed of sound is related to air temperature T byv=331ms√TK273K=331ms√1+TC273°C.
