Physical and Chemical Properties of Matter Notes

A substance is defined by its own unique set of physical and chemical properties.

Physical Properties
Characteristics that can be observed without changing the identity of the substance itself. Examples:
area absorbency brittleness
boiling/condensation point conductivity color
density ductility elasticity
hardness luster length
magnetic attraction malleability mass
melting/freezing point odor solubility
shape texture transparency
temperature volume viscosity
Physical Change
These occur when the substance changes its physical form or appearance, but not its composition. Examples include shape changes, phase changes and dissolving.
Chemical Properties
Characteristics a substance shows when it interacts with, or transforms into other substances. This is a substance's ability to change into another substance. Examples:
flammability reaction with water reaction with acids
corrosiveness tendency to form compounds
Chemical Change
When a substance (or substances) is converted into a different substance (or substances). This is also called a chemical reaction. This is the process by which a substance changes. After a chemical change the physical and chemical properties of the substance change.
