Let's define a perfect elastomer as (i) one that obeys Hooke's, F=kl, where k is not a function of / but is a function of T: and (ii) one for which au al (f) Show that k ak where K is a true constant. Does the Hooke's law constant increase or decrease with increasing temperature? Is this consistent with the empirical finding mentioned above? Why? -(g) Calculate w for an extension at constant T from -0tol I in terms of 1, T, and K. (h) Define a heat capacity at constant / (C,) in terms of q, T, and 1. (i) Give C, in terms of U, T, and 1.
