a169483b830c9acd4b27591d4f27113fWhat is a physical property of a substance and what are physical changes?

A physical property is a property of a substance that does not involve a chemical change.

Examples include: shape, melting/boiling point, solubility, density, color, weight, mass, volume, state of matter, or hardness.

A physical change is a change that alters the form or appearance of a material but does not make the material into another substance.

Evidence of physical changes include: change of shape, weight, color, volume, hardness, state of matter, texture (life if you sand a piece of wood, it is still wood but smoother).
