Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is

complex relationship with an applied magnetic field (spin glassbehavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. They includecopper‚ aluminium‚ gases‚ and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state. The magnetic state (or phase) of a material depends on temperature (and other variables such as pressure and the applied magnetic field) so that a material may exhibit more than one form of

Properties and changes are used to describe matter. A property is a trait of matter‚ when that sample of matter is in a fixed state. There are two different types of properties: physical properties and chemical properties. A change is something that alters the properties of a substance. There are two types of changes: chemical changes and physical changes. A physical property is a property that can be observed without changing the makeup (or composition) of a substance.
