Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
A melting candle demonstrates which reaction?
A melting candle is an example of a physical change, not a chemical reaction. The process involves a solid candle turning into liquid wax due to the application of heat, with no change in the chemical composition of the wax molecules.
When you roast a marshmallow is it a physical change or a chemical change?
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.
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 part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
Is melting wax physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
Is a candle melting a physical change or a chemical change?
It is a physical change because when it melts it is still a candle just a melted one
Is a candle melting chemical or physical?
The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.

How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
Is a burning a marshmallow a physical or chemical change?

Why is melting of covered candle a physical change while burning of a candle wick a chemical change?
This is because a candle will change its whole form and stay that way, which is a physical outer change. And a candle wick only burns, it doesn't change it's appearance.
Is candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
