The question asks about the experimental measurement of specific gravity and its practical applications. We need to identify the correct instruments used for measuring specific gravity and understand its relevance in various fields.
Specific gravity is indeed measured using a hydrometer or a pycnometer. Its applications include assessing material quality, purity, and concentration, which aligns perfectly with the practical uses discussed above.
The behavior of substances when mixed, particularly in terms of layering or settling, is primarily governed by their densities. Density is defined as mass per unit volume. When two immiscible substances are mixed, the one with higher density will sink, and the one with lower density will float.
C) Substances with higher densities tend to settle at the bottom, while those with lower densities float on top when mixed with others. This statement accurately describes the behavior of immiscible substances based on their relative densities. The denser substance sinks, and the less dense substance floats.

The question asks to identify the true statement about density. We need to recall the definition of density and its properties to evaluate each option.
B) Density remains constant regardless of the amount of substance. This is because density is an intensive property, meaning it does not depend on the quantity of the substance.
The question asks for the correct definition of volume. We need to evaluate each option based on the fundamental definitions of physical quantities.
Correct Option: C) Volume measures the space occupied by an object.
The question asks about the reference substance used to define specific gravity. Specific gravity is a dimensionless quantity that indicates how dense a substance is compared to a reference substance. We need to identify the standard reference substance for this comparison.
Correct Option: C) Specific gravity compares the density of a substance to the density of Water. Water at \(4^\circ\text{C}\) is the standard reference for specific gravity of liquids and solids.
