Question

It's hardness and intensive or ext extensive physical property

Answer 1

Hardness is considered an **intensive physical property**. Intensive properties are those that do not depend on the amount of substance present. Hardness is a characteristic that describes how resistant a material is to deformation or scratching, and it remains the same regardless of the size or shape of the sample. In contrast, extensive properties, such as mass or volume, do depend on the amount of substance present.
