Use the formula `v=sqrt((gamma P)/(rho))` to explain why the speed of sound in air
(a) is independent of pressure, (b) increases with temperature, (c) increases with humidity.

How does the speed v of sound in air depend on the atmospheric pressure P?

Assertion : Speed of sound in gass is independent of pressure of gas. Reason : With increase in temperature of gas speed of sound will increase.

Graph between speed v of sound in air and pressure P at a constant temperature is given by

Velocity of sound in air (i) increases with temperature (ii) decreases with temperature (iii) increases with pressure (iv) is independent of pressure

Every ^(@)C rise in temperature, the speed of sound increases by

The speed of longitudinal waves 'v' in a given medium of density p is given by the formula v=sqrt(lambda P/rho) Use this formula to explain why the speed of sound in air increases with temperature.
