The Carnot cycle (reversible) of gas is represented by a pressure-volume curve as shown in the figure. Consider the following statements:

I. The area \(ABCD\) = The work done on the gas
II. The area \(ABCD\) = The net heat absorbed

One mole of a diatomic ideal gas undergoes a cyclic process \(ABC\) as shown in the 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:
               
1. The change in internal energy in the process \(BC\) is \(-500R.\)
2. The change in internal energy in the whole cyclic process is \(250R.\)
3. The change in internal energy in the process \(CA\) is \(700R.\)
4. The change in internal energy in the process \(AB\) is \(-350R.\)
