The rms speed of an ideal diatomic gas at temperature is . When gas dissociates into atoms then its new rms speed becomes double. The temperature at which the gas dissociated into atoms are:
View answer and explanation
Correct option: D
Option D (2 T) is correct because when the diatomic gas dissociates, the molar mass halves, and the rms speed doubles, leading to a doubling of the temperature.

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
