food coloring dropped in a glass of water will eventually spread from the
concentration near the top to the
concentration at the bottom.
because the molecules in

around, diffusion happens slower than in
, which has

Explanation:

1. Food coloring spreads via diffusion, moving from an area of high concentration to low concentration. When first dropped, the top has a high concentration, and the bottom has a low concentration.
2. Solids have molecules that vibrate in place but do not move freely, while liquids allow more molecular movement. This means diffusion is slower in solids than in liquids.

Answer:

1. Food coloring dropped in a glass of water will eventually spread from the high concentration near the top to the low concentration at the bottom.
2. Because the molecules in solids vibrate but don't move around, diffusion happens slower than in liquids, which has freely moving molecules.
