cooling curve analysis (Excel) spreadsheet and lab report

Process attached file (time and temperature data) and develop cooling curves for each sample. There should be 1 Composite graph of all three time vs temperature curves, individual graphs of each unknown Pb-Sn alloy showing the time-temperature curve, cooling rate curve as a secondary axes, and identification of melting points and local solidification time.

and then wright a lab report for it.
