Changes in energy are always followed by a specific chemical or physical change in the surrounding environment.
The natural environment undergoes a great deal of change, including the evaporation of water and the formation of condensation and rainfall, among other things. All of these transformations are accompanied by a change in state. The old bonds in the reactants are broken, and new bonds in the products are formed as a result of certain reactions.
Chemical change: An overview
An example of a chemical change is a chemical process in which one or more chemicals undergo modifications, resulting in the formation of new substances or a new structure. As a result, chemical transformations result in the production of new substances.
A chemical change is the transformation of one material into another, the formation of new materials with different properties, and the formation of one or more new substances. If one substance reacts with another to generate a new substance, the reaction is known as a reaction (synthesis or either decomposes to form more substances). The oxidation reaction is an example of a chemical change that results in the occurrence of a chemical reaction.
They are generally irreversible unless they are reversed by other chemical processes. Examples of chemical changes include the chemical reaction that develops the dye in the colour and the chemical reaction that causes a chemical change in the hair. Organic changes, inorganic changes, and biochemical changes are the three types of chemical changes that can occur.
Examples of Chemical changes
Chemical Changes Involving Organic Compounds
Complex carbon compounds in which one or more carbon atoms are covalently connected to atoms of other elements are referred to as organic compounds. Examples of chemical transformation involving organic compounds are provided in the next section.
The combustion of natural gas
This is a textbook illustration of a combustion reaction. Methane gas is included in the definition of natural gas. Water and carbon dioxide are produced when methane combines with the oxygen present in the environment. As a result, it is an example of chemical transformation.
Ripening of Fruits
It entails a succession of modifications. Ethylene can be found in fruits. A rise in ethylene production occurs when fruit is injured or when it is removed from the tree. This results in the synthesis of new enzymes, which in turn react with the chemical present on the fruit to provide the desired effect. As a result, the fruit may undergo a number of transformations. Some of the modifications are detailed below.
• The fruit grows juicier and softer as time passes.
• The colour of the fruit’s outer skin changes as a result of the degradation of chlorophyll in the fruit.
• The aroma of ripe fruit fills the air.
Chemical Changes Involving Inorganic Compounds
The chemical changes involving inorganic substances are those that occur when compounds and elements undergo reactions that do not involve carbon atoms. Some instances of chemical transformations involving inorganic substances are discussed further down this page.
Formation of Steel
It is an unstoppable process that cannot be stopped. Steel is created through the addition of various other elements in specific amounts to iron, with carbon serving as the basic constituent. This results in the synthesis of new substances, which is why it is referred to as a chemical transformation. Compared to iron, the newly created compounds have different physical and chemical properties.
The igniting of a fireworks display
Metal nitrates are present in fireworks, resulting in the formation of burning compounds. When a firecracker is lit, combustion occurs, resulting in the formation of a new substance as well as the emission of light and heat from the explosion. As a result, it can be characterised as a chemical transformation.
Photosynthesis
Photosynthesis is a process in which plants transform light energy into chemical energy, and it is the most common type of photosynthesis. A chemical process that occurs in plants is known as photosynthesis. As a result of this transformation, plants produce carbohydrates and oxygen out of water and carbon dioxide.

Conclusion
Changes are a very unpredictable or uncertain phenomenon, and depending on your point of view, they can be for the better or for the worse. Every day, we witness various objects change in our environment, such as ice melting, food cooking, and so on. In certain circumstances, you will receive the original ingredient back, but in others, you will not receive it back. Some changes are gradual, while others are rapid; some are caused by nature, while others are the result of human activity. The world around us is changing rapidly. For example, plants growing on your balcony may change colour occasionally, and leaves drying on trees may be seen occasionally.
