Answer
For Process 1 to have zero work done, it must occur at constant volume. Therefore, we can tick the 'constant volume' box under Process 1.
Step 2
Process 2 in which the change in internal energy is zero

Answer
For Process 2 to have a change in internal energy of zero, it must be an isothermal process where internal energy remains constant. Hence, we tick the 'isothermal' box under Process 2.
