Assertion: The change in air pressure effect the speed of sound.
Reason: The speed of sound in a gas is proportional to the square of pressure.
Reason: The speed of sound in a gas is proportional to the square of pressure.
View answer and explanation
Correct option: D
If both Assertion and Reason are false
Option D (If both Assertion and Reason are false) is correct because the speed of sound is independent of pressure changes when temperature is constant, and the speed of sound is proportional to the square root of pressure, not the square.

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 is the velocity of sound in air and is the rms velocity, then Four particles have velocities . The root mean square of the particles is (in ) The translational degrees of freedom and rotational degrees of freedom of molecule are: On any planet, the presence of atmosphere implies (= root mean square velocity of molecules and escape velocity) At a given temperature, the pressure of an ideal gas of density is proportional to
