1.	A gas mixture consists of 2 moles of oxygen and 4 of Argon at temperature T. Neglecting all vibrational modes, the total internal energy of the system isA. 4RTB. 15RTC. 9RTD. 11RT
Answer» Correct Answer - D `U=n_(1)(f_(1))/(2)RT+n_(2)(f_(2))/(2)RT` =`2 xx(5)/(2)RT+4xx(3)/(2)RT` `=5RT+6RT` `U=11RT`
