Question
One mole of diatomic ideal gas undergoes a cyclic process ABC as shown in figure. The process BC is adiabatic. The temperatures at A, B and C are 400 K, 800 K and 600 K respectively. Choose the correct statement
Options
A.The change in internal energy in whole cyclic process is 250R
B.The change in internal energy in the process CA is 700R
C.The change in internal energy in the process AB is - 350R
D.The change in internal energy in the process BC is - 500R
Solution
ᐃU = nCvᐃT = 1 × 
ᐃT
For BC, ᐃT = - 200 K
⇒ ᐃU = - 500R
ᐃT For BC, ᐃT = - 200 K
⇒ ᐃU = - 500R
