if the pressure of gas is doubled then speed of sound is
Answers
Two swings and two misses, for your question. Let me help you out.
As density of a gas increases, the speed of sound increases within that gas because sound travels faster in a more dense medium. BUT, as pressure increases in a medium, the speed of sound decreases. The net change of the speed of sound in a gas remains the same.
Internet published speed of sound charts are inaccurate at best. They are approximations of the speed of sound based on the changes of temperature. They generate a nice little chart that will include the large change in temperature (1.5–2.5 C per 300m of altitude) and the slight change due to the estimated change in humidity. The speed of sound in a gas changes a lot with temperature.
If your question comes from an aviation viewpoint, Do not associate anything with indicated airspeed, calculated airspeed, or mach rating. Bernoulli's law, is about moving air, not moving sound thru air.
Explanation:
if the pressure of gas is double d then the speed of sound will double or become half or not affected or increase by four times
