Which of the following processes is expected to have the largest increase in entropy?
Dissolving salt in water
Melting ice
Boiling water
Sublimation of solid iodine
Sublimation of solid iodine to gas involves a phase change from solid to gas, which has a significant increase in disorder, thus the largest increase in entropy.

Q: Which of the following processes is expected to have the largest increase in entropy?
Solution: Sublimation of solid iodine to gas involves a phase change from solid to gas, which has a significant increase in disorder, thus the largest increase in entropy.
Steps: 6
Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Identify the processes being compared. Look for processes that involve changes in states of matter (solid, liquid, gas).
Step 3: Recognize that solids are more ordered than liquids, and liquids are more ordered than gases.
Step 4: Determine which process involves a change from a more ordered state to a less ordered state.
Step 5: In this case, sublimation of solid iodine to gas means the solid iodine (ordered) turns into iodine gas (disordered).
Step 6: Conclude that this process has the largest increase in disorder, and therefore the largest increase in entropy.
