Question

The molecular weight of a polymer is related to this quantity and its theoretical maximum according to the Flory–Fox equation. For 10 points each:
[10m] Name this quantity that is indicated by a change in the rate of thermal expansion in dilatometry. This temperature is indicated by a point on a graph’s x-axis where a steep slope in heat capacity begins.
ANSWER: glass-transition temperature [prompt on T-sub-g]
[10h] A paradox named for this scientist states that extrapolating the heat capacity of supercooled liquids below the glass-transition temperature results in a crystal–liquid entropy difference of zero. This scientist also discovered the hydrophobic effect.
ANSWER: Walter Kauzmann [or Walter J. Kauzmann; accept Kauzmann’s paradox]
[10e] Kauzmann’s solution to his own paradox is that liquids undergo this action before the Kauzmann temperature. This process is usually induced by adding a nucleation seed and results in materials with long-range order.
ANSWER: crystallization [accept recrystallization]
