Assertion: An ideal gas has infinitely many molar specific heats.
Reason: Specific heat is amount of heat needed to raise the temperature of 1 mole of gas by .
Reason: Specific heat is amount of heat needed to raise the temperature of 1 mole of gas by .
View answer and explanation
Correct option: B
If both Assertion and reason are true and the Reason is not a 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 while both statements are true, the reason doesn't explain why an ideal gas has infinitely many molar specific heats.

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
