A gas mixture consists of

4 \mathrm{~mol}

of oxygen and

6 \mathrm{~mol}

of argon at temperature

T

. Neglecting all vibrational modes, the total internal energy of the system is

View answer and explanation

Correct option: D

19 R T

Option D (19RT) is correct because it sums the internal energies of oxygen (diatomic) and argon (monoatomic) gases, considering their respective degrees of freedom.

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
