The speed of sound in air is 332 meters per second. If the pressure is increased to double then the speed of sound will be

If the pressure is doubled, the speed of sound in air remains; option [B] 332 m/sec. The speed of sound in a gas like air is primarily determined by its temperature. Under normal atmospheric conditions, changes in pressure do not significantly alter the speed of sound. This is because the relationship between pressure and the speed of sound in gases is indirect and complex, with temperature having a more pronounced effect on the density and elasticity of the medium.

In practical terms, doubling the pressure in air at a constant temperature does not double the speed of sound. It would require extreme changes in pressure or modifications in temperature to significantly alter the speed of sound in air. Thus, under the conditions given, the correct answer remains [B] 332 m/sec, reflecting the stability of the speed of sound in air under varying pressure conditions within normal ranges.
