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.
Ripple in water is a surface wave. A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmissionâthe materialâis limited. Therefore, oscillating material does not move far from its initial equilibrium position.
