Kinds of physical property

Answer 1

Density, hardness, melting point, boiling point, thermal conductivity, electrical conductivity, mechanical properties, magnetic properties, refraction index and other optical properties, specific heat capacity, etc.

Answer 2

Physical properties of matter include characteristics such as color, density, temperature, state of matter (solid, liquid, gas), melting point, boiling point, and conductivity. These properties can be observed and measured without changing the composition of the substance.

Answer 3

Intensive - independent of quantity (like density)

Extensive - depends on quantity (like mass, volume)
