- Sugar molecules will be more concentrated at the bottom of the container because the sugar molecules are heavier than water and will sink.
- Sugar molecules will be more concentrated at the bottom of the container because sugar dissolves poorly or not at all in water.
-
The process responsible for blue dye becoming evenly distributed in the water is diffusion because the dye separates into smaller particles and mixes with water.
-
The rate of diffusion decreases because there is less room for the particles to move.
