2 Density is the ratio of the mass of an object to its volume. 3.4Determining DensityDensity is the ratio of the mass of an object to its volume.
3 3.4Determining DensityDensity is an intensive property that depends only on the composition of a substance, not on the size of the sample.
4 Density and Temperature 3.4Density and TemperatureDensity and TemperatureHow does a change in temperature affect density?
5 Density and Temperature 3.4Density and TemperatureExperiments 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.
