CAIE IGCSE Physics 1.4.4 Whether one liquid will float on

Practise using density data for non-mixing liquids to decide which liquid floats and how layers arrange in a container.

Exam points

calculate liquid densities from mass and volume tables before ranking layers
explain that the less dense non-mixing liquid floats above the denser liquid

[Maximum number: 2]

Oil of density $0.80 \mathrm{~g} / \mathrm{cm}^{3}$ is poured gently onto the surface of water of density $1.0 \mathrm{~g} / \mathrm{cm}^{3}$ . The oil and the water do not mix.

Describe and explain the final position of the oil relative to the water.
