4. In the following one-component phase diagram: 19 OCCE MEIHO 5 +2 (a) Label the regions corresponding to the vapor, liquid and solid phases. labeled below. +2 cnr. 2 (b) Identify the point in the graph in which all three phases have the same chemical potential. Sant D in the graph has all turce Phases in the same chemical potential (c) What would happen to the melting point if the pressure is decreased? The lights would also increase. #jorett mo "ure mb CH)- Pressure (atm) 73 52 (4) (d) What would happen to the boiling point if the pressure is increased? The gases would also increase (e) Using the phase rule, calculate the number of degrees of freedom at the triple point, T3. ? (f) Describe all changes that you expect to observe if the sample is initially at 205 K, 1 atm and then it is isothermally compressed to a pressure of 52 atm in terms of physical state and the trends of the thermodynamic variables (P, T, V).
