Relative density, also called specific gravity, [1] [2] is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
Relative density is defined as the ratio of density of the substance to the standarnd which is either air for gases and water for liquids or solids.
Relative density (RD) is the ratio of the density of a substance to the density of water. It is also known as specific gravity (SG). Because it is a ratio, relative density or specific gravity is a unitless value.
Relative density, on the other hand, is the density of a substance to the density of the standard substance. It is also known as specific gravity. In this article, we will learn the concept, its different properties, different steps involved in the calculation process and various applications.
The relative density of solids or liquids is the ratio between the mass of a volume of a substance to be examined, determined at 20°C, and the mass of the same volume of water, determined at 4°C. The relative density has no dimension. Read about types of density at Vedantu.com.
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 density of a substance to a reference substance.
Relative density, also known as specific gravity, is the ratio of the density of a substance to the density of a reference material, typically water at 4°C and 1 atmosphere of pressure.
The ratio of the density of a substance to the density of some reference substance. For liquids or solids it is the ratio of the density (usually at 20°C) to the density of water (at its maximum density).
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, typically water at 4°C. It provides insight into how heavy or light a substance is in relation to water, helping to predict whether it will float or sink when placed in water.
Definition of relative density. 1) Relative density (also known as specific gravity) is a measure of the density of a material. It is dimensionless, equal to the density of the material divided by the density of water.
