Final answer:
In Chemistry, physical properties like density, boiling point, and color are measured to understand a substance's characteristics without changing its composition. Density, for instance, helps determine purity, while boiling point and electrical conductivity predict behavioral changes under varying conditions.
Step-by-step explanation:
In the field of Chemistry, physical properties of substances are those that can be observed or measured without altering the substance's chemical composition. Properties like density, boiling point, and electrical conductivity are important because they can help scientists identify substances and predict their behavior under different conditions. For instance, density can be an indicator of purity for a substance, boiling point provides information about the substance's state changes, and electrical conductivity can determine if a substance can conduct electricity. Moreover, color, taste, and texture are sensory properties that can be discerned without changing the substance. On the other hand, volume, mass, and temperature are fundamental measurements in Chemistry, providing essential information about the quantity and energy state of a substance. Lastly, properties such as magnetic susceptibility, solubility, and malleability describe how a substance interacts with magnetic fields, solvents, and physical forces, respectively.
