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

Answer
In an isothermal process, the temperature remains constant, so the change in internal energy is also zero for an ideal gas. Therefore, we tick the box for 'isothermal' in 'Process 2'.
