검증된 단계별 안내1
Understand that density is a physical property that relates how much matter is packed into a given space.
Recall the definition of density as the ratio of mass to volume, which tells us how much mass is contained in a unit volume of a substance.
Express the density mathematically as \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Recognize that weight divided by temperature, volume divided by mass, or amount per unit area do not correctly describe density.
Conclude that the best definition of density is 'the mass of a substance divided by its volume.'
