A polymer is under research investigation to calculate its kinetics behavior to be used in a petrochemical plant. The crystallization temperature (Tc) and melting temperature (Tm) have been found in this research for multiple trials as the following table: You have been asked to do the following tasks: A) Estimate equilibrium melting temperature (Tm) by providing XY. dimensions. (Use Excel). B) The heat of fusion and fold surface interfacial energy have been found to be h=3.551010 J/m3 and e=18.3J/m2, respectively. Find the variations of the lamella thickness (Fold) of this polymer (in nm unit) during the crystallization. (Use Excel)
