Q1. Imagine you are working for an automotive manufacturer and are selecting plastic materials for various components. Draw the structure of a material you might use for a soft touch plastic. Now draw the structure of a material you might use in the drive train (i.e., an engineering plastic). What characteristics are you engineering into the material? Q2. Based on what you know about the calorimetry of melting and crystallization, do you expect melting to be endothermic or exothermic? What about condensation? Can we say anything general about heat flow in the process of forming bonds, covalent or van der Waals?

The class is Thermodynamics and Kinetics of Materials, the section is on surface energy using "Phase Transfromations in Metals and Alloys" by Porter, Easterling, and Sharif. The first image shows the problem. My understanding from Eq 3.1 is that the free energy of the 2 dimensional rectangle (with no bulk and two surfaces) would be G=2AY (Y being gamma [free energy per unit area] in the text). The second image is the pertinant section. The problem gives two length variables, each with an assigned free energy (Y) and says the area is constant. The solution claims the Gibbs Energy is G=2(l1Y1+l2Y2) which I don't understand if the area should be the product of the lengths, not the sum.
