Activity 4.5.1. As we said before in class, entropy has many different indicators: volume, temperature, speed, etc. For this reason, we can have many different entropy changes going on at once. The Gibbs Free Energy is a way to see whether our entropy changes result in energy leaving or entering our system. (delta G) = (delta H) - T(delta S) A) In a rubber band, the polymers are only very weakly bound to each other along their "sides." Thermal energy near room temperature is more than sufficient to easily break these side-to-side bonds. Likewise, the polymers can bend very easily at many points along their length where the monomers are attached to one another. These bonds don't break, however, they simply allow swiveling to easily occur. B) 1) If a string supporting a small mass is vibrated vigorously and randomly, its effective length is shortened. 2) The string does work on its hanging mass, W is a positive value because we know the gravitational potential energy for the mass has increased, so energy must have been put into the system.
