Answer
The condition where work done is zero corresponds to a process where the volume remains constant, as no expansion or compression occurs. Therefore, the appropriate choice for Process 1 is 'constant volume'.
Step 2
Process 2 in which the change in internal energy is zero

Answer
The condition where the change in internal energy is zero occurs in an isothermal process, where the temperature remains constant. Hence, for Process 2, the correct selection is 'isothermal'.
