Density vs. Volume: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on January 16, 2024
Density is mass per unit volume of a substance, while volume is the amount of space an object occupies.

Key Differences

Density refers to how closely packed the particles of a substance are. In contrast, volume measures the total space that a substance or object occupies.

The density of an object remains constant at a given temperature and pressure, irrespective of its size. Volume, however, can vary greatly depending on the size and shape of the object.

Density is a property that helps determine whether an object will float or sink in a fluid. Volume is a measure used to determine how much space an object or substance fills.

Density is expressed in units like grams per cubic centimeter (g/cm³), while volume is measured in units such as liters or cubic meters.

Density is an intrinsic property of a material and does not change unless the material's composition changes. Volume can change with alterations in temperature and pressure.
