Final answer:
The correct answer is option a.Knowing the volume and specific gravity of a substance allows you to determine the weight of the substance.
Step-by-step explanation:
When you know the volume and specific gravity of a substance, you gain valuable insights into its mass or weight. Specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water). It provides information about how much denser or lighter the substance is compared to water.
By multiplying the volume of the substance by its specific gravity, you can calculate its weight. This is a crucial parameter in various scientific and industrial applications.
For example, in construction, understanding the weight of materials is essential for structural integrity. In chemistry and physics, knowing the weight allows for accurate measurements and formulations.
The specific gravity and volume alone, however, don't provide information about the color, chemical formula, or melting point of the substance.
These properties require additional analysis and experimentation. Color is related to the substance's interaction with light, the chemical formula involves understanding its elemental composition, and the melting point is determined by the substance's molecular structure and intermolecular forces.
In summary, knowing the volume and specific gravity enables the determination of the substance's weight, a fundamental parameter with broad applications, but it doesn't directly reveal other specific properties like color, chemical formula, or melting point.
