Relative density, also called specific gravity, [1][2] is a dimensionless quantity defined as the ratio of the density (mass divided by volume) of a substance to the density of a given reference material.

Relative density (or specific gravity) is the ratio of the density of a substance to the density of water. It tells us whether a substance is heavier or lighter than water.

Jul 23, 2025 · Relative density (also known as specific gravity) is the ratio of the density of a substance to the density of a reference substance, typically water. It is a dimensionless quantity because it …

Relative density is the ratio of the density of a specific substance to the density of a reference substance, typically water for liquids and solids, and air for gases. It is a dimensionless quantity …

Jun 21, 2023 · Definition: The relative density (R.D.) of a substance is the ratio of the mass or weight of any volume of it to the mass or weight of an equal volume of water. The second name for relative …

Density and relative density are both important concepts in the study of materials and their properties. While density measures the mass per unit volume of a substance, relative density compares the …

On the other hand, relative density is defined as the ratio between the density of a body and the density of some other reference body. What is the common unit of density? Grams per cubic centimetre. At …

Relative density is a comparative measure of the density of a substance to the density of a reference substance. Usually, for liquids, the relative density is measured with respect to water at its densest …

Relative density is a dimensionless number that determines whether an object will sink, float, or stay suspended in water. With examples like ice and iron, this video breaks down the formula and...

Relative density, also known as specific gravity, is a dimensionless quantity that compares the density of a substance to the density of a reference substance, usually water. It is defined as the ratio of the …
