Phase Diagram Experiment The following figures and tabulated data were obtained during the Phase diagram experiment for Pb-Sn using DSC machine. Tables 1-4 shows the wt% composition of Sn in Pb at different temperatures. 1) Use figures 1 and 2, and Table 1 to plot the Temperature (°C) against wt% composition of Sn in Pb. 2) Use the figures and 2, and Table 2 to plot the Temperature (°C) against wt% composition of Sn in Pb on Figure 1 : 1 00wt% of Sn ( Pure Sn) Figure 2: 100wt% of Pb (Pure Pb) Table 1: Four different wt% compositions ofSn in Pb 83 183 83 Table 2: Three different wt% compositions ofSn in Pb 183 97.5 Table 3: Three different wt% compositions ofSn in Pb 30 Table 4: Two different wt% compositions ofSn in Ph 97.5 30

Answer 1
