Physical Property Definition. A physical property is defined as a characteristic of matter that may be observed and measured without changing the chemical identity of a sample. The measurement of a physical property may change the arrangement of matter in a sample, but not the structure of its molecules.
Physical and Chemical Properties Physical properties are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties. The difference between a physical and chemical property is straightforward until the phase of the material is considered. When a material changes from a solid to a liquid to a vapor it seems like them become a difference substance.
