The chemical changes are the changes which lead to change in the chemical composition example, cooking, rusting etc. The examples of chemical properties are the heat of combustion which is the energy released when a compound undergoes complete combustion (burning) with oxygen, or Chemical stability which is determined if a compound will react with water or air as the stable chemical substance will not react. The chemical properties are referred to as that property which lead to the change in the chemical structure. Similarly, the physical properties of acid which are most likely to change when it undergoes any reaction are its sour taste, the change in its color (litmus paper). It gets affected in case of soil erosion. For example, the physical properties of soil changes include the texture, porosity, density etc. These changes did not result in any change of the chemical composition unlike the chemical change. The reaction involving any change in these extensive or intensive properties is called physical properties. The intensive ones are color, density while the extensive properties are the volume, mass etc. The intensive properties are not seen with the naked eyes while the extensive ones are easily observed. Some of the other physical change includes:Īs we discussed, the physical properties are the properties which are either intensive or extensive. However, there is no chemical change involved here. This change will include two types of physical changes as it will change the state of matter from solid to liquid and mixing of pieces of fruits. For example, if we blend two fruits to make a juice. Some changes also include more than one type of change in their properties. It only changes the physical state of the substance but doesn't change the chemical composition of the substances. The other examples of physical properties can be measured or demonstrated by studying color, density, volume and mass of the substances. The example of physical property can be explained with the help of freezing water, when we freeze the water, it will still remain water, however, only the physical state will change. These can be estimated without controlling the chemical identity of the substances. It is important to note that physical properties are both intensive or extensive properties. The examples of intensive properties are color or density which do not depend on the amount of matter. The examples of extensive properties are volume or mass depending on the amount of the measured matter. These properties are either intensive or extensive or they can be classified as physical or chemical. For example, non metals have different ways of reacting towards acid from metals as the properties of metals and non-metals differ.

There are different ways to observe the physical and chemical properties of the substances. Every substance reacts differently as all of them consist of different physical properties.

It is important to study the properties of substances to understand their nature. These properties of matter are either chemical or physical and further, these physical properties are either extensive or intensive. And every matter in this universe consists of physical and chemical properties which change when it undergoes reaction.

Anything that occupies space and has some mass is called matter.
