first shrink and then swell

swell

shrink

remain the same size

- Placing dried raisins in a concentrated salt solution can cause water to move due to osmosis.

- Option 1: first shrink and then swell suggests dynamic osmosis, but typically it’s not two-step.

- Option 2: swell is unlikely, as water is drawn out of the raisins.

- Option 3: shrink occurs because water inside the raisins moves out to the higher salt concentration.

- Option 4: remain the same size suggests no osmotic activity, which is improbable.

The correct answer is Option 3: shrink.
