However, if you mix a red and white substance together and get blue, then you may have a chemical reaction. That’s just what happens when you mix the colors red and white together. If you mix white and red together and get pink or light red, then that’s probably not a sign of a chemical reaction. Now, a chemical property on the other hand can only be observed after a chemical reaction has taken place-so after the chemical has gone through an identity change. These, along with others, are all examples of physical properties of matter, but these do not change the chemical identity of the substance. Along with boiling point, and melting point, this includes:Įlectric charge – this is a property that causes matter to encounter force when inside of a magnetic field.ĭensity – this describes how close or how far apart the atoms within a substance are Other Physical PropertiesĪ physical property is anything you can hear, see, touch, smell, or measure and observe in some form without changing the chemical identity of the substance. When ice melts, the only thing changing is its physical state. When ice melts into liquid water, the chemical identity doesn’t change. So, if there is an observable change, but the chemical identity doesn’t change, then you have a physical change. The chemical property hasn’t changed, only its physical property. For instance, when water (H2O) boils, so when it converts from a liquid to a gas or water to steam, it is still water. Boiling Point of a SubstanceĪ substance’s boiling point is a physical property. Let’s take a look at some examples of physical properties of matter. A physical property describes an observable change in a substance’s characteristics but does not affect the chemical makeup of that substance. Now, properties are just characteristics of something. Being able to make observable distinctions is a very good and necessary tool in life, and this absolutely applies to the sciences. What we observe helps us to make distinctions. Maybe you’ve distinguished a chocolate lab from a golden retriever, because the chocolate lab was brown, had shorter and more compact hair. Have you ever classified something based on what you observe about it? Perhaps you’ve distinguished a dog from a cat based on the dog’s larger structure, flappy ears, and longer head shape.
