As one of these two quantities varies, the graph of a polymer's elastic modulus as a function of the other shifts sideways but keeps its shape according to these quantities' superposition principle. These two quantities appear on a diagram abbreviated CCT that is used when one action occurs at a constant rate. In a partial differential equation, the derivative of one of these two quantities with respect to the other equals the Laplacian (luh-PLASS-ee-un) of one of them times a diffusivity constant. These two quantities are plotted on the axes of an isothermal transformation diagram. The derivative of one of these quantities with respect to the other is on one side of the heat equation. The dependence of one of these quantities on the other is given by Newton's Law of Cooling. For 10 (10[1])points, name (-5[1])these (10[1])two (-5[2])quantities measured in seconds and (10[1])kelvins. (10[5])■END■
