if a rock sinks, it is more dense than water. Liquid Density examples based upon differences in mass or weight per unit volume. Density of a liquid with a constant volume, varies according to the weight. The higher the weight, the higher the density.

Explanation:

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne
