The syllabus states:
Candidates should be able to:
1 describe density as mass per unit volume and
recall, manipulate and use the formula:
density =
mass/ volume
2 investigate the effect of temperature on (PA) density of water
3 investigate the effect of salinity on density of (PA) water
4 explain how changes in density of liquids result in the formation of convection currents
5 explain the effect of temperature on water density and volume in terms of particle theory
6 explain, in terms of density, why colder water generally lies beneath warmer water
