Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.

A physical change is when a substance undergoes a process whereby its physical features change but its chemical features stay the same. By definition, any change in the state of matter is a physical change.

a usually reversible change in the physical properties of a substance, as size or shape: Freezing a liquid is a physical change.

Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.

Both: They both invlove changes in the state of matter. They both have energy changes. There are new things made either way, no matter if the chemical composition is changed or not.

How are physical and chemical changes similar and different? (compare and contrast) (Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter …

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

A description of some common mechanical and physical properties will provide information that product designers could consider in selecting materials for a given application.

• Conductivity.
• Corrosion Resistance.
• Density.
• Ductility / Malleability.
• Elasticity / Stiffness.
• Fracture Toughness.
• Hardness.
• Plasticity.

Physical Properties

• color (intensive)
• density (intensive)
• volume (extensive)
• mass (extensive)
• boiling point (intensive): the temperature at which a substance boils.
• melting point (intensive): the temperature at which a substance melts.

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.
