Answer:
Diagram 1
Step-by-step explanation:
The correct diagram that depicts the liquid layers in the cylinder would be diagram 1.
The density of a substance is a measure of how heavy the substance is. Hence, a liquid that is heavier than water (with higher density) would sink in water while a liquid that is less dense than water would float on it.
Therefore, based on the density of the karo syrup (1.4 g/mL), it would take the bottom space in a cylinder, followed by water (1.0 g/mL) while vegetable oil with 0.91 g/mL would float on the former two.
The correct diagram is 1.
