Assertion: On increasing temperature, internal energy of monoatomic gas increases.
Reason: Thermal energy increases only random motion of gas molecules.
Reason: Thermal energy increases only random motion of gas molecules.
View answer and explanation
Correct option: C
If assertion is True but the Reason is False
Option B (If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion) is correct because increasing temperature does increase internal energy, and thermal energy increases random motion, but the reason isn't the *only* factor for internal energy increase.

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
