b) [10%] Develop an algorithm and present it in flowchart form for the pure case only. Any calculation/equation must be explicitly presented in your flowchart. Present 4 desktop tests for temperature/pressure combinations where the result is: (1) zone 1, (2) zone 2, (3) zone 3, and (4) between zone 2 and zone 3"

(c) [10%] Implement a function in Python for the pure case. The function must be called with temperature and pressure (2 parameters) and must return the phase in which the material is. Present 4 desktop tests that return different results and their respective screenshots (prtscrns).
