Detailed explanation-1: -An intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties include temperature, refractive index, density, and hardness of an object.

Detailed explanation-2: -Physical changes alter the physical properties of the matter (e.g., , shape, volume, density, state, etc.), but the molecular structure remains the same.

Detailed explanation-3: -Those physical properties which are not affected by the amount of matter present in a substance are called size-independent properties. Melting point, boiling point, and density are some examples of size-independent properties.

Detailed explanation-4: -Physical changes involve changing the physical properties of a substance. Some examples of physical properties include color, volume, shape, and phase changes.

Detailed explanation-5: -Physical properties are often characterized as intensive and extensive properties. An intensive property does not depend on the size or extent of the system, nor on the amount of matter in the object, while an extensive property shows an additive relationship.
