Question

what is effect of pressure on velocity of sound​

Answer 1

Answer:

Change in pressure has no effect on velocity of sound in a gas, so long as temperature remains constant; because ;

P/ρ = constant; as long as temperature is constant.

Answer 2

Explanation:

Humidity has little effect on the speed of sound, nor does air pressure by itself. Air pressure has no effect at all in an ideal gas approximately. This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature
