स्तिर दाब पर, किसी एकलपरमाणवीय आदर्श गैस के \(7\) मोल का तापमान \(40\,K\) बढ़ाया जाता है। उपरोक्त प्रक्रम में गैस की आंतरिक ऊर्जा \(..........\,J\) बढ़ जाएगी । (दिया है, \(R =8.3\,JK ^{-1} mol ^{-1}\) )

  1. A \(5810\)
  2. B \(3486\)
  3. C \(11620\)
  4. D \(6972\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(3486\)

Step-by-step Solution

Detailed explanation

For a quasi-static process the change in internal energy of an ideal gas is \(\Delta U = nC _{ V } \Delta T\) \(= n \times \frac{3 R }{2} \times \Delta T\) [molar heat capacity at constant volume for mono atomic gas \(=\frac{3 R}{2}\) ]…
