3.4 Determining Density • Density is the ratio of the mass of an object to its volume.
3.4 Determining Density • Each of these 10-g samples has a different volume because the densities vary.
3.4 Determining Density • Density is an intensive property that depends only on the composition of a substance, not on the size of the sample.
Intensive property is a property that depends on the type of matter in a sample, not the amount of matter.
Determining Density • Simulation 1 • Rank materials according to their densities.
3.4 Density and Temperature • Experiments show that the volume of most substances increases as the temperature increases. Meanwhile, the mass remains the same. Thus, the density must change. • The density of a substance generally decreases as its temperature increases.
