A physical property is any property that can be measured and whose value is the description of the state of a physical system. The measurement of a physical property may change the arrangement of matter in a sample, but not the structure of its molecules. Any property you can see, smell, touch, hear or otherwise detect and measure as color, shape etc.
A chemical property may only be observed by changing the chemical identity of a substance. This property measures the potential for undergoing a chemical change. Examples of chemical properties include reactivity, flammability and oxidation states.
