Question: 1 / 400

How is density defined?

mass × volume

mass + volume

mass ÷ volume

Density is defined as the mass of an object divided by its volume. This relationship can be expressed mathematically as density = mass/volume. When you quantify density, you are essentially determining how much mass is contained in a given volume of a material.

This definition is crucial because density helps in identifying substances and understanding their behavior in different environments. For example, materials with lower density will float on those with higher density, which is fundamental in fields such as physics and engineering.

In the context of the other options, multiplying mass by volume or adding mass and volume does not yield a meaningful measure of density since density specifically describes the ratio of mass to volume. Similarly, dividing volume by mass reverses the relationship and does not reflect the definition of density.
