Explain that water is made up of tiny particles, called molecules, which are too small to see. These particles are always moving, even in very cold water. Since water molecules move, the molecules help mix the food coloring. However, the color mixed faster in the hot water than it did in the cold.
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases. When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. For example, if the cell is submerged in saltwater, water molecules move out of the cell. If a cell is submerged in freshwater, water molecules move into the cell.
