Question

Interpretation Questions Q5: Phase diagram is a graphical representation of the equilibrium phases as a fuction of temperature, pressure, and composition. The following phase diagram represents the state of matter of a substance in relation to the temperature and pressure 1.000 100 10 Solid Liquid Pressure am) 1.04 0.1 0.01 Vapor 0.001 40 60 80 100 120 140 160 180 Temperature 1. Identify the sublimation point at standard atmospheric pressure. How many intensive vasriable(s) we need to identify in order to descripe the state of the system at this point. 2. If location A on the diagram represents a state of matter at pressure of l atm and temperature of 140 C. What would happen to the state of matter if this location was under 0.01 atm while keeping the same teperature, provide short explaination. 3. Identify by locations (find the locations) of two points on the diagram that represent two differrent state of matters at equilibrium. The two locations share one constant intensive variable while changing the pressure. a. What are the states of matters of the two locations? b. Why are they happening? c. What are the degrees of freedom of each?
