The energy equation for a reversible non-flow process can be expressed as d d q u p v δ = + , where q is the heat transfer per unit mass, u is the internal energy per unit mass, p is the pressure, and v is the mass specific volume. This energy equation is not in exact differential form. It can be made exact differential by multiplying with the following integrating factor: (T is the absolute temperature)
- A. 1 p
- B. 1 v
- C. 1 T
- D. 1 uT
Answer: C. 1 T
