A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.Leaves yellow as the result of a biochemical process, meaning it is a chemical reaction that occurs in a living thing. Even though some people think the change in the color of tree leaves in fall is an example of a physical change, the color change actually occurs because of chemical changes inside the leaf.Some examples of physical properties are color, shape, size, density, melting point, and boiling point.

Complete answer: Chemical changes occur when the substance’s composition is changed. When bonds are broken and new ones are formed a chemical change occurs. When two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical change is probably occurring. A change in color is not always a chemical change.

In each of these examples, there is a change in the physical state, form, or properties of the substance, but no change in its chemical composition.

A chemical change is any change that results in the formation of new chemical substances with new properties. For example, hydrogen reacts with oxygen to form water. This is a chemical change. 2H₂ + O₂ → H₂O. Hydrogen and oxygen are both colourless gases, but water is a liquid at ordinary temperatures. EXAMPLES.Again, this is an example of a physical change. Figure 4.5.1 4.5. 1: Ice melting is a physical change.

Definitely, but it is not a good indicator of telling you which might have occured. Explanation: Color change is a good way to tell that a change has occurred, and there's really nothing more to say about that. However, I would warn you against using color change as a firm identifier of either physical or chemical changes.
