Chapter 22, Problem 155CP

(a)

Interpretation Introduction

Interpretation: The effect on temperature on the stretching of rubber band is to be stated and whether the stretching is an exothermic or endothermic process is to be explained in terms of intermolecular forces. Also, the sign of ΔS and ΔG for stretching the rubber band is to be stated with the molecular explanation for the sign of ΔS for stretching.

Concept introduction: Rubber is a polymer (long chain molecules) made from organic compound isoprene. The molecules in rubber are arranged in a tangled up position than an aligned position and due to thermal motion they lose their alignment and go back to their tangled state and this is called an elastic contact caused by an entropic force.

To determine: The effect on temperature on the stretching of rubber band.
