I need help to finish this lab and fill in the blanks or at least the the part that says post lab data analysis and after...I have given the known data in the tables
i need help with the post lab questions and the blank spots on the tables ASAP please

Plot temperature versus time. Do not have Excel plot a trend line through the data. Indicate the appearonce of the first crystal and Tr an each cooling curve, and record the values in the appropriate data tables. Turn in a printed copy of each cooling curve with your lab report. Do not print raw data from MeasureNet. Sample Calculations. (For credit, show your work for each of the following somple colculations, including units. Additiond calculations must be performed to complefe all data fables, but you do not have to show a sample of each of these, Record all colculated results in the appropriate data toble.)
