Assertion (A) : If a gas container is placed in a moving train, the temperature of gas will increase.
Reason (R) : Kinetic energy of gas molecules will increase.
Reason (R) : Kinetic energy of gas molecules will increase.
View answer and explanation
Correct option: D
If Assertion is false but the Reason is true.
Option D is correct because the assertion about gas temperature increase in a moving train is false, while the reason about increased kinetic energy of gas molecules is true.

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
