It is a chemical change because inside the stove the Kerosene gets burnt and

produces flames and energy in the form of heat and light. We cannot get back

Kerosene again from the products of is combustion. Hence, we call the combustion of Kerosene as a Chemical Change.

A candle burning is a chemical change because the heat from the flame causes the wax to vaporize and react with oxygen in the air to produce carbon dioxide, water vapor, and heat. This chemical reaction results in the formation of new substances that have different properties from the original wax.

Kerosene burning is part of the chemical process of combustion or a reduction reaction where the hydrocarbon kerosene is combined with oxygen and a primer (heat) to form carbon dioxide and water as byproducts

Think of it this way:

Physical changes can be undone: if you cut a piece of wood, you can put it back together and it's still all there.

However, you can't un-burn a candle because the energy has been released as heat and light.

Burning is a chemical reaction, an oxydation.


Is burning candle getting shorter physical or chemical change?

Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.


Is candle burning physical change?

Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!


What is burning candle it is physically Chang or chamically?

Burning a candle involves a chemical change, as the wax is being oxidized by the oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process is irreversible and results in the formation of new substances, which is characteristic of a chemical change.

Why burning candle is chemical change?

When a candle burns, the wax undergoes a chemical reaction with oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process involves breaking and forming chemical bonds, resulting in a new substance being created. Therefore, burning a candle is considered a chemical change.
