The Tin-Bismuth phase diagram is shown below. DSC was used to analyse three samples in the Sn-Bi system.

Sample 1 has the composition 40 wt% Bi – 60 wt% Sn,

Sample 2 has the composition 57 wt% Bi – 43 wt% Sn, and

Sample 3 has the composition 100 wt% Sn.

Using the information from the phase diagram, draw graphs of the expected DSC curves for the three samples on heating from 50°C to 300°C. Label the axes and curves
