What is a Chemical Change?
Those changes which lead to a change in the chemical composition of the matter are termed chemical changes. This change leads to the formation of new products with different chemical compositions.
- The molecular composition of matter is changed, and new product formation takes place in chemical change.
- The chemical and physical properties of the products formed are different from the original reactants.
- A chemical change may be accompanied by the release or absorption of energy.
- Chemical change in which energy is absorbed is called endothermic reaction while the reaction in which energy is released is called exothermic reaction.
- The mass of products may or may not be the same as the mass of reactants due to the loss of some mass as energy.
- Chemical change is permanent and cannot be reversed through simple physical processes. The irreversible nature of chemical change is due to the breakage and formation of new bonds that take place during a chemical change.
Difference Between Physical And Chemical Change
Physical and chemical changes are two different aspects of changes that are happening on the earth. When any object’s physical composition changes then we call that physical change and when any object’s chemical composition changes we call that chemical change. But physical change and chemical change are not limited to that. So it is important to understand about different properties of physical and chemical changes.
In this article, we will explore the difference between Physical and Chemical change, along with their examples, and real-life applications.
