Question

The figure below gives the force magnitude F versus stretch distance x for a rubber band, with the scale of the F axis set by Fs = 1.55 N and the scale of the x axis set byxs = 2.80 cm. The temperature is 2.00°C. When the rubber band is stretched by x = 1.95 cm, at what rate does the entropy of the rubber band change during a small additional stretch?

Answer should be in J/K*m

The figure below gives the force magnitude F versus stretch distance x for a rubber band, with the scale of the F axis set by Fs = 1.55 N and the scale of the x axis set byxs = 2.80 cm. The temperature is 2.00A degree C. When the rubber band is stretched by x = 1.95 cm, at what rate does the entropy of the rubber band change during a small additional stretch? Answer should be in J/K*m

Explanation / Answer

work done = F . dX

= 1.55 . ( 2.8 - 1.95 ) * 10^-2 J

it is equal to Q

dS/dt = Q / Temp
