Assertion: Maxwell speed distribution graph is symmetric about most probable speed.
Reason: rms speed of ideal gas, depends upon its type (monoatomic, diatomic and polyatomic).
Reason: rms speed of ideal gas, depends upon its type (monoatomic, diatomic and polyatomic).
View answer and explanation
Correct option: D
If both assertion and reason are false
Option D is correct because both assertion and reason are false. The Maxwell speed distribution graph is asymmetric, and the rms speed of an ideal gas depends on temperature and molar mass, not the type of gas (monoatomic, diatomic, etc.).

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
