Resumen de Using Latex Elastomer to Illustrate Euler's Chain Relationship

Fred R. Hilgeman, Ana A. Alcaraz

• Designed for the physical chemistry laboratory, this experiment uses the properties of an elastomer, latex, to illustrate the experimental validity of Euler's chain relationship. Considering the length of an elastomer to be a function of its tension and temperature, one can use this mathematical relationship to show that (δt/δT)l(δl/δt)T(δT/δl)t = -1. This is done by measuring each of the terms in the equation and determining their slopes. Within experimental error, the product of these slopes is -1.
