At constant pressure, which of the following is true?

View answer and explanation

Correct option: D

v \propto \frac{1}{{\sqrt \rho }}

Option D (

v \propto \frac{1}{{\sqrt \rho }}

) is correct because at constant pressure, the speed of sound is inversely proportional to the square root of the density.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If

c_s

is the velocity of sound in air and

c

is the rms velocity, then Four particles have velocities
