JEE Mains · Physics · STD 11 - 12 . kinetic theory of gases

यदि एक बंद पात्र में \(27^{\circ} \mathrm{C}\) पर हाइड्रोजन अणुओं की संघट्ट आवृत्ति \(\mathrm{Z}\) है, तो उसी निकाय की \(127^{\circ} \mathrm{C}\) पर संघट्ट आवृत्ति _______ होगी।

  1. A  \(\frac{\sqrt{3}}{2} \mathrm{Z}\)
  2. B \(\frac{4}{3} \mathrm{Z}\)
  3. C \(\frac{2}{\sqrt{3}} \mathrm{Z}\)
  4. D  \(\frac{3}{4} Z\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\frac{2}{\sqrt{3}} \mathrm{Z}\)

Step-by-step Solution

Detailed explanation

Assuming mean free path constant. \(\mathrm{f} \propto \mathrm{v} \propto \sqrt{\mathrm{T}}\) \(\frac{\mathrm{f}_1}{\mathrm{f}_2}=\sqrt{\frac{\mathrm{T}_1}{\mathrm{~T}_2}}=\sqrt{\frac{300}{400}}\) \(\mathrm{f}_2=\sqrt{\frac{4}{3}}=\mathrm{f}_1=\frac{2}{\sqrt{3}} \mathrm{Z}\)
