Speed of sound wave in air.

1.	Speed of sound wave in air.
Answer» is independent of temperature. increases with pressure. increases with INCREASE in humidity. DECREASES with increase in humidity. SOLUTION :Velocity of sound in air is `v = sqrt ((gamma P)/(rho )) implies v PROP (1)/(sqrtrho)` Density of dry air is less than that of MOIST air. Hence velocity of sound in dry air would be more than that in moist air (humid air).
