Question 7 of 20 Mapoob Sapling Learning this question was written by the faculty at University of Arizona The four points A, B, C, D in the Potential Energy-Configurations (PEC) diagram below represent four potential states of a mixture of a pol correspond to a polymer that is highly insoluble in the solvent and its solubility slightly increases wher increasing the temperature r with a certain solvent. Select the combnation of states that would Potential Energy O O O O O O A (Mixed) B (Unmixed) B (Mixed) A (Unmixed) A (Mixed) D (Unmixed) D (Mixed) A (Unmixed) C (Mixed) B (Unmixed) B (Mixed) C (Unmixed) Number of Configurations

Explanation / Answer

Potential energy is the lowest energy state. Any body which is streched, defromed, or dissolve into one-another then it store a certain amount of energy. This energy is restored in the body itself at the lowest energy level.

Here we seen there are 4 points A,B,C,D in the grpah of Potential energy configuration.

1) A(mixed) B(unmixed) - correct

beacuse here A and B are at different potential by considering one as reference.

2) B(mixed) A(unmixed) - wrong

Since A is at lower potential then B so it can be mixed completely.

3) A(mixed) D(unmixed) - wrong

both cannot be compared as both A and D having different potential in context with different reference leevl.

4) D(mixed) A(unmixed) - wrong

Already mentioned in question and reason is same as above.

5) C(mixed) B(unmixed) - wrong

both cannot be compared as both C and B having different potential in context with different reference leevl.

6) B(mixed) C(unmixed)

Same as above.
