Consider the following isobaric process for the refrigerant $507$A:

$$ State $1$ S$=1\mathrm{.}25$ KJ$/$Kg$.$K $,$ and P$1=300$Kpa

$$ State $2$:$$ T$2=50$degrees Celsius

a$)$ Represent the process in both attached diagrams $($draw the states and process directly in the diagram$).(2\mathrm{.}5$ points$)$

b$)$ Explain the reason for your choice in the diagram, for each of the thermodynamic states. $(2\mathrm{.}5$ points$)$

c$)$ What is the state of the fluid in each one $($compressed liquid, saturated, superheated vapor...$)?$ Reason your answer from the diagram. $(2\mathrm{.}5$ points$)$

d$)$ Determine the grades of freedom of each state. What means the value obtained in each case, from the point of view of the number of properties required?$(2\mathrm{.}5$ points$)$
