Answer:
The speed of sound in a gas depends on the following
factors Density At constant pressure, the speed of sound in a gas is inversely
proportional to the square root of its
density.
i.e.. Speed of sound
(b) Temperature The speed of sound in a gas is directly
proportional to the square root of its absolute temperature.
i.e.. Speed of sound
(c) Humidity Sound speed is greater in humid or moist air
than in dry air.
(d) Pressure Pressure has no effect on the speed of sound
in a gas.
