Create a material balance table by calculating the weight of each input and output component. Feel free to make additional assumptions if necessary.

6.3 A polymer sample is initially heated above its melting point, then rapidly quenched below its glass transition temperature. About 10 mg is then placed in a pan and a DSC experiment is conducted. A temperature ramp is used at 10 °C/min so that the polymer passes through its Tg and Tm values (curve 1). It is then cooled very slowly, allowing annealing to occur. A second heating cycle (from the same starting temperature also at 10 °C/min to above the Tm) will reveal a different DSC curve (curve 2). The sample is then treated the same as after the first cycle- cooled very slowly to anneal. A third run is conducted, starting below Tg and ending above Tm, but at a temperature ramp rate of 50 °C/min (curve 3). A. Qualitatively, draw three thermogram curves as label each as 1, 2 or 3. Label Tg & Tm B. Explain differences in the curves in the three DSC thermograms; compare the integrated areas of the melting peaks in each thermogram.
