Question 7 • Chemistry A.1 - F26 - Jacob Metsker

Which statement describes a system that consists of sugar crystals dissolving in water?

Answer
A
The system becomes more ordered and has an increase in entropy.
B
The system becomes more ordered and has a decrease in entropy.
C
The system becomes more disordered and has an increase in entropy.
D
The system becomes more disordered and has a decrease in entropy.

Explanation

When sugar dissolves, its molecules spread throughout the water instead of remaining in an orderly crystal. This makes the system more disordered, and greater disorder corresponds to increased entropy. Therefore, the correct statement is that the system becomes more disordered and has an increase in entropy.
