Physical Property- A physical property is any property that can be observed or measured without changing the composition of matter. These include color, odor, melting point, boiling point, density, etc.
Chemical Property- A chemical property is a property that can be measured or observed only when matter undergoes a change to become an entirely different matter. These include reactivity, flammability, toxicity, etc.
Extensive Property- It is a physical property of matter that changes as the amount of matter changes. Examples of extensive property include volume, mass, weight, etc.
Intensive Property- It is a physical property of matter that does not depend on the amount of matter. Examples of intensive property include boiling point, density, color, odor, etc.
Density- The density of a substance is its mass per unit volume, i.e.,
We use grams per cubic centimeter (g/cm3) for the densities of solids and liquids, and grams per litre (g/L) for gases.
