Mass and density make up the physical properties of any substance. Mass indicates the amount of material an object is made from, while density indicates the space that it fills. Density indicates to how tightly packed the molecules of the substance are. Mass measures the amount of matter present in an object, which is usually expressed in grams or kilograms.

Unlike weight, the mass of something is not influenced by gravity, but without gravity, a particular matter will no longer have weight, but it still has mass. The bulk of a substance is its mass unit per volume. The concentration of water has been taken as one, and an object with a higher density will sink in water, while an item having a density less than water will float on it.

One of the best examples of applications of mass and density is observed in the ocean water, where water at the surface is hotter than water at the base. Warm water is lighter than cold water, and it rises to the surface.

Mass and density are two aspects that are related to all types of matter. Mass is the amount of matter. Density is the ratio between mass and volume. One key difference between the two is the property of it. The mass has an extrinsic property. This means that for it to be defined, the matter must be present. Density is intrinsic, meaning that it is not required for matter to be present for it to be defined. Another difference between them is how they are measured. Mass is measured in kilograms, while density is measured in kilograms per cubic meter, which is an SI measurement.
