What phenomenon occurs when raisins are placed in water, and how can it be explained?

Options

  1. AOsmosis - Water molecules move into the raisins, causing them to swell due to the concentration gradient.
  2. BDiffusion - Raisins absorb water through their semi-permeable membranes.
  3. CEvaporation - Water evaporates from the raisins, causing them to increase in size.
  4. DSublimation - Raisins change from a solid to a gaseous state when placed in water.

Correct answer

A. Osmosis - Water molecules move into the raisins, causing them to swell due to the concentration gradient.

Step-by-step solution

Correct Option is : (A) Osmosis - Water molecules move into the raisins, causing them to swell due to the concentration gradient.
