The velocity of sound in a gas depends on its pressure and density . Obtain the relation between velocity , pressure and density.

Write the relation between pressure and density of gas.

Give the relationship between pressure and density of gas.

Velocity of sound in a gas does not depend on the pressure of the gas. Why?

Velocity of sound in a gas….. With increase of pressure

What si the relationship between pressure and density of a gas ?

The velocity (v ) of sound in a gas depends on the pressure (p) and density ( sigma ) of the gas. Using dimensional analysis establish a relation between v,p and sigma .
