CAIE IGCSE Physics 1.4.4 Whether One Liquid Will Float on Questions

Practise comparing liquid densities to predict the vertical order of immiscible liquids and explain why a lower-density liquid floats above a higher-density liquid.

Exam points

Compare density values to predict the order of immiscible liquids and explain why lower-density liquids float.

[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.
