Final answer:
Physical Property is a characteristic observed or measured without changing a substance's chemical identity, such as solubility and melting point. Chemical Properties describe behavior during chemical changes, like reactivity and flammability.
Step-by-step explanation:
The term Physical Property refers to a characteristic of a substance that can be observed or measured without changing its chemical identity. These include attributes such as color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point. For instance, silver has the physical properties of being shiny and a good conductor of electricity, while salt's properties include being dull, brittle, and conducting electricity when dissolved in water.
However, Chemical Properties are different as they describe the behavior of a substance when it undergoes a chemical change to form new substances; examples include flammability and reactivity with acids. These properties are intrinsic to the substance and dictate how it will react under different conditions.
