Final answer:
The chocolate-chip batter is an example of a suspension where solid particles are dispersed in a liquid but do not dissolve, causing them to settle at the bottom.
Step-by-step explanation:
The chocolate-chip batter is an example of a suspension. In a suspension, solid particles are dispersed in a liquid, but they do not dissolve. This causes the particles to settle out over time, which is why the chocolate chips sink to the bottom of the mixing bowl.
This phenomenon can be explained by the difference in density between the chocolate chips and the pancake batter. Since the chocolate chips are denser, they sink to the bottom under the force of gravity.
Other common examples of suspensions include soil in water, sand in water, and orange juice with pulp.
