AP EAMCET · PHYSICS · Kinetic Theory of Gases
The average kinetic energy of \(\mathrm{H}_2\) molecules at \(300 \mathrm{~K}\) is \(E\). At the same temperature the average kinetic energy of \(\mathrm{O}_2\) molecule is
- A \(E\)
- B \(\frac{E}{4}\)
- C \(\frac{E}{16}\)
- D \(16 E\)
Answer & Solution
Correct Answer
(A) \(E\)
Step-by-step Solution
Detailed explanation
Average kinetic energy of \(\mathrm{H}_2\) molecules at \(\begin{aligned} 300 \mathrm{~K} & =E \\ E & \propto T \end{aligned}\) Since, Hence, at same temperature average kinetic energy of \(\mathrm{O}_2\) molecule will be same as \(E\).
