(b)
Interpretation:
A system is to be defined and the open-system energy balance for each case is to be simplified. Whether the nonzero heat and shaft work terms are positive or negative is to be predicted.
Concept introduction:
A system in which there exchange of matter as well as energy between the system and its surroundings is known as an open system. Due to increase or decrease in the mass of the overall system, the energy stored inside the system may also change.
