Trang 5Liquid Density
Liquids are made up of tiny particles The density of a liquid depends on how tightly packed together these particles are
Different liquids have different liquid densities.
Water has a density of 997 kg/m³.
Some liquids have a higher density than water These liquids will sink below the water, leaving the water to float above.
Other liquids have a lower density than water These liquids will float above the water.
