Definition of Chemical Change
A chemical change refers to a process in which one or more substances are transformed into new and different substances with distinct properties.
It involves the breaking and forming of chemical bonds, resulting in the creation of new molecular structures.
This transformation occurs through a chemical reaction, often accompanied by the release or absorption of energy.
Unlike a physical change, which only alters the physical state or appearance of a substance, a chemical change involves a fundamental change in the composition and nature of the matter.
To better understand this concept, let’s consider an everyday example. When we burn a candle, we witness both physical and chemical changes taking place.
The physical change occurs as the solid wax melts into a liquid state due to the heat from the flame.
This change can be compared to freezing ice cream, where a solid substance changes into a liquid form.
However, the true chemical change occurs when the heat triggers the combustion of the wax.
The hydrocarbons in the wax react with oxygen in the air, resulting in the production of carbon dioxide and water vapor, as well as the release of light and heat.
This chemical reaction is similar to the process of digesting food in our bodies, where the substances undergo a chemical transformation to provide energy.
In summary, a chemical change involves the formation of new substances through the breaking and forming of chemical bonds.
It is characterized by a fundamental change in the composition and properties of matter.
Like burning a candle, chemical changes often entail the release or absorption of energy.

Explanation of Burning Process
When a candle burns, it undergoes a fascinating series of transformations involving both physical and chemical changes.
The burning process can be best understood by breaking it down into two distinct stages: the physical change and the chemical change.
Firstly, the physical change occurs when the solid wax of the candle is exposed to the heat from the flame.
The intense heat causes the wax to undergo a phase transition from its solid state to a liquid state. It’s a bit like how ice melts when heated, transforming into water.
I remember observing this change when I last lit a candle.
As the flame danced and flickered, the solid wax gradually turned into a mesmerizing pool of liquid, slowly spreading and filling the area around the wick.
Secondly, the chemical change takes place once the heat from the flame triggers the combustion or burning of the wax.
This chemical reaction is known as combustion, where the wax reacts with oxygen present in the surrounding air.
It’s similar to how wood burns in a fireplace when exposed to heat and oxygen.
During combustion, the hydrocarbons in the wax are broken down, releasing energy in the form of light and heat.
The process is exothermic, meaning it releases more energy than it consumes. This is what causes the candle to emit a warm, cozy glow that is so characteristic of them.
To support the analogy, think of the candle’s wick as a fuel source, similar to the kindling used in a fireplace.
Just as kindling helps sustain a fire by providing a steady supply of fuel, the wick draws up liquid wax from the pool, enabling a continuous supply of fuel for the flame to burn.
Additionally, much like how burning wood results in the conversion of solid wood into gaseous byproducts, burning a candle converts solid wax into gaseous substances, mainly carbon dioxide and water vapor.
In conclusion, the burning of a candle involves both physical and chemical changes.
The physical change occurs when the wax melts into a liquid state, while the chemical change occurs when the wax undergoes combustion, releasing light and heat.
This process can be likened to the burning of wood in a fireplace, where new substances are formed as the solid fuel is transformed into gaseous byproducts.
Understanding the intricate science behind the burning process adds a deeper appreciation for the mesmerizing allure of candlelight.
