1. Temperature: The degree of hotness or coldness of a substance. A change in temperature can cause matter to expand or contract.

2. Phase: The state of matter, whether solid, liquid, or gas. Matter can transition between these phases through processes like melting, freezing, boiling, condensation, and sublimation.

3. Shape: The form or outline of an object. Solids can be deformed (changed shape) by external forces. Liquids and gases take the shape of their container.

4. Volume: The amount of space an object occupies. Changes in temperature or pressure can affect the volume of matter.

5. Density: The mass of a substance per unit volume. Density can be influenced by changes in temperature, pressure, or composition.

6. Color: The way a substance interacts with light. Changes in color can indicate changes in the substance's composition or structure.

Important Note: These are physical properties, meaning that changes in these properties do not alter the chemical composition of the substance. For example, melting ice (solid water) into liquid water doesn't change the chemical composition of H2O, just its physical state.
