Answer 1

Answer:

Explanation:

The Elastic Band. Consider the thermodynamics of a stretchable 1D polymeric system (an "elastic band") as shown in the schematic below: 4. Work is performed by an external stretching force, f, acting on thelength of the elastic band, L During stretching, the volume of the elastic band remains constant (i.e., PV work is notrelevant to the internal energy of the elastic band).

Determine the final temperature of the elastic band upon reversible adiabatic stretching to four times its equilibrium, unstretched length at an initial temperature of 298 K, where: d. G-G. (constant length heat capacity) CL 175 K Lo
