Final answer:
The statement that flow work can be expressed in terms of other properties is true, as it is related to fluid pressure and change in volume, which are thermodynamic properties. option a is true
Step-by-step explanation:
Flow work can indeed be expressed in terms of other thermodynamic properties. In a fluid system, flow work is the energy required to move fluid into or out of a system boundary. This work is necessary because the fluid has to push against the pressure of the system to move in or out. Flow work (PdV work) is defined by the equation PdV, where P represents the pressure of the fluid, and dV is the change in volume.
Considering the equation, we can clearly see that flow work is related to pressure and change in volume, which are both thermodynamic properties. Furthermore, the first law of thermodynamics relates this flow work to other energy changes within the system. Therefore, the initial statement that flow work can be expressed in terms of other properties is true. option a is true
