JEE Mains · Physics · STD 11 - 12 . kinetic theory of gases
A gas mixture consists of \(2\) moles of oxygen and 4 moles of neon at temperature \(T\). Neglecting all vibrational modes, the total internal energy of the system will be \(...........\,RT\)
- A \(8\)
- B \(16\)
- C \(4\)
- D \(11\)
Answer & Solution
Correct Answer
(D) \(11\)
Step-by-step Solution
Detailed explanation
\(\left( C _{ v }\right)_{\operatorname{mix}}=\frac{ n _1 Cv _1+ n _2 Cv _2}{ n _1+ n _2}\) \(\left( C _{ v }\right)_{\operatorname{mix}}=\frac{2 \times \frac{5}{2} R +4 \times \frac{3}{2} R }{2+4}=\frac{11 R }{6}\)…
