A motif is a recurring symbol which takes on a figurative meaning. We see them in books, films, and poems. In fact, almost every text commonly uses the literary device of the motif. A motif can be almost anything: an idea, an object, a concept, a character archetype, the weather, a color, or even a statement.
The Specific Gravity of liquids and solids is defined as a dimensionless unit which is the ratio of density of a material to the density of water at a given temperature, where density is defined as the materialâs mass per unit volume and is measured in kg/m 3.
Definition: Specific gravity is the ratio of the density of a substance to the density of water. Example: The specific gravity of pure water at 4 Â°C is 1. Specific gravity is a unitless value. Return to the Chemistry Glossary Index. Up Next. Up Next.
