A physical change is the melting wax. A chemical change is the burning wick and wax. Remeber, the wax will melt before it burns.
Melting of candle is a physical change.Burning of candle is a chemical change.
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
A melting candle is a physical change A burning one is a chemical
The melting of the candle.
Chemical change. A physical change can be undone. There is no way to "unburn" a candle.
when wax of the candle burns it is a physical change but when wick of the candle burns it is a chemical chang
The only physical change is that there is a candle and there isn't afterwards. The chemical change is in the candle burning.
Combustion of candle wax, heat loss within a system, and physical/chemical changes that occur are a result of energy transformers.
The physical state of a candle changes from the solid state to the liquid state.
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
When the wax candle burns, the wax which melts can be changed to its solid state on cooling, which is a physical change. The burning of wax releases some gases which cannot be reversible. Hence it is a chemical change.
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
Physical change: 1.) Melting Ice Cream 2.) Sharpening Pencil Chemical Changes: 1.) Rust 2.) Burning Candle
It is a chemical change.
There is a chemical and physical. physical :
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.
Chemical =the candle burns Phisycal=the wax melt
physical- cutting something curling your hair making steam freezing something Chemical- burning a candle toasting toast peroxide on a cut.
Yes, burning a candle is a chemical change. New chemical compounds are being formed as the reaction continues. The paraffin in the candle is a hydrocarbon chain, and it is "breaking down" chemically using oxygen from the air to form (idealy) carbon dioxide and water. But there are also physical changes that take place at the same time. Phenomena during the candle burning: - melting (physical phenomenon) - evaporation (may be considered a chemical but also a physical phenomenon) - oxydation - reaction with oxygen, burning (chemical phenomenon) - thermal decomposition (chemical phenomenon)
The 'melting' is physical, the 'burning' is chemical.
