Answer:
C) Dependent on the mass flows in and out.
Explanation:
Lets take control volume(CV)
Take
=inlet mass flow rate
=exit mass flow rate
If we take unsteady flow process then inlet mass can not be equal to exit mass.Some mass can store if inlet mass flow rate is high and exit mass flow rate is low.
So mass of control volume
.
so above we can say that mass of control volume dependent on inlet and exit mass.
