Rubber band 6 their experiment is used to teach data analysis methods by using multiple approaches to extract the parameters in an equation of state for the rubber band.
Rubber band equation of state.
So we have the first law.
I have non zero tension at equilibrium.
In this paper we introduce.

Equation of state of a rubber band.
Rubber band as a function of temperature and extension using a space heater to change the temperature of the rubber band 6 their experiment is used to teach data analysis methods by using multiple approaches to extract the parameters in an equation of state for the rubber band.
However there is no thermodynamic analysis of the resulting values nor do they address the applicabil ity of the equation of state.
When the bands are stretched the energy is increased and the polymers untangle until they reach a local maximum of their length and a local minimum of entropy.
However there is no.
The cross linked polymers of a rubber band begin in a chaotic low energy tangled state.
Du t ds fdl dq dw the work done on the elastic band is 0 as it is held at a fixed length.
Implies du dq dt c.
2 if the equation of state for a rubber band is given by where θ is a constant and l is the length of the rubber band determine the chemical potential θ e s l n 2 2 μ t l n.
3 begingroup i have the following question that i attached in png format.
Also show this equation of state satisfies the gibbs duhem equation.
3 consider a rubber band under tension f with length per mole lln.

Individual 4 carbon backbone units are forced into rotational conformations that have longer end to end distances and this restricts the number of conformations states that are thermally accessible.
We show and analyze the variables thermodynamic formulation of rubber band heat engine to accommodate the experimental data so that the equation of state heat work and efficiency are not only.
I have done part a but i am having difficulties in part b when i proceed according to the book.
