One mole of an ideal diatomic gas undergoes a transition from A to B along a path AB as shown in figure. The change in internal energy of the gas during the transition is

  1. -20 KJ
  2. 20 J
  3. -12 KJ
  4. 20 KJ

Solution

Change in internal energy 

∆U=f2nRT2-T1=f2p2v2-p1v1⇒∆U=522×6-5×4=-20 KJ
