Part2 6.3 Draw phase diagrams for the following types of systems. Label the regions and intersections of the diagrams, stating what materials (possibly compounds or azeotropes) are present and whether they are solid liquid or gas. (a) One component, pressure- temperature diagram, liquid density greater than that of solid. (b) Two component, temperature-composition, solid-liquid diagram, one compound AB formed that melts congruently, negligible solid-solid solubility. 6.6 Label the regions of the phase diagram shown below, state what substances (if compound give their formula) exist in each region, label the phase of each substance) 6.12 Sketch the cooling curves for the isopleths a and b in Fig. 6.41 (8 th edition) or Fig 5.66 (9 th edition)

6.4 Phosphorus and sulfur form a series of binary compounds. The best characterized are P 4 S 3 , P 4 S 7 , and P 4 S 10 , all of which melt congruently. Assuming that only these three binary compounds of the two elements exist, (a) draw schematically only the P/S phase
