the physical change is -the shape of the candle changes,some of the wax becomes liquid to solid.
chemical change-the wick is burned
*Hi just wanted to say that this person above is wrong...I mean, the wick burning would be a chemical change because it is combustion. They are wrong because the wick doesn't actually burn.The wax is absorbed by the wick which cools it off. Eventually the wick becomes too long and the top of it dries out and falls off into the wax. Fact being, the wax vapor burns. You should do some more individual research for details because there is more. Thanks!

During the burning of a candle, the physical change is the melting of the wax and the solid wax turning into liquid wax. The chemical change is the reaction between the liquid wax and oxygen in the air, leading to combustion and the production of carbon dioxide, water vapor, and heat.

Is burning a candle wick a physical property?
No, burning a candle wick is a chemical change, not a physical property. Physical properties describe characteristics that can be observed without changing the substance's identity, while chemical changes involve the rearrangement of atoms and result in a new substance being formed.
What form of energy is a candle?
Heat and light energy.
What type of energy changes take place when a candle burns?
When a candle burns, the chemical potential energy stored in the wax is converted into heat and light energy through the process of combustion. The heat energy generated causes the surrounding air to warm up, while the light energy is emitted as a visible flame.
What type of energy is in a lit candle?
The energy in a lit candle is primarily in the form of chemical energy. When the candle burns, this chemical energy is converted into heat and light energy.
What is energy of a candle?
The energy of a candle comes from the chemical reactions that occur when the candle burns. This process releases heat and light energy in the form of a flame. The energy produced by a candle can be used for lighting or heating purposes.
How is a burning candle both physical and chemical changes?
because of the digestions system of the candle is visible
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
To prove that the burning of a candle is a physical and chemical change, you can observe the physical changes such as the melting of the wax and the formation of soot. Additionally, you can analyze the chemical changes by noting the production of carbon dioxide and water vapor during the combustion process. By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
Is it physical or chemical change a candle wax falls on the ground and cools?
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
What is the physical and chemical change that occurs when a birthday candle is lit on a cake?
When a birthday candle is lit on a cake, the physical change that occurs is the wax of the candle melting into liquid form due to the heat. The chemical change involves the burning of the wax vapor to produce carbon dioxide and water vapor, along with heat and light.
Is candle wax hardening a physical or chemical change?
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
Is candle melting physical or chemical?
Physical.
What are the chemical properties of a candle?
What are the physical properties of unlit candle
Is burning a candle wick a physical property?
No, burning a candle wick is a chemical change, not a physical property. Physical properties describe characteristics that can be observed without changing the substance's identity, while chemical changes involve the rearrangement of atoms and result in a new substance being formed.
Is candle wax melting chemical or physical change?
The melting of candle wax is a physical change because it is a reversible process where the wax changes from a solid to a liquid state without forming new substances.
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!
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
