Assertion: Absolute zero temperature is not the temperature of zero energy
Reason: Only the translational kinetic energy of the molecules is represented by temperature.
Reason: Only the translational kinetic energy of the molecules is represented by temperature.
View answer and explanation
Correct option: A
If both Assertion and reason are true and the Reason is the correct explanation of the Assertion
Option B (If both Assertion and reason are true and the Reason is not a correct explanation of the Assertion) is correct because absolute zero doesn't mean zero energy, and temperature only represents translational kinetic energy.

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
