Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.

When a candle burns both physical and chemical changes take place Identify these changes?
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!
What type of reaction occurs when a candle is burned?
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
How can you explain the physical change of a burning candle using the big idea of energy?
Well it is simple when you think about it reallly. The wax melting from the heat of the flame is the physical change. It will turn turn into a liquid and then later solidify.
What type of energy does a candle have?
Candle wax is a form of chemical energy.
What physical property makes wax good for making sculpture molds?
melting point
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.
Is burning wax a physical or chemical change?
Burning wax is a chemical change. If you are burning something, it will always be a chemical change.
Is wax hardening a chemical change?
NO... physical
Is wax melting a chemical or physical or chemical property?
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
Is wax melting a physical or a chemical?
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Is Melted Wax A Chemical Change chemical Property?
It is physical change. It is a physical property. There is no change in the composition of the was as it becomes liquid.
Is melting wax an chemical change?
no because the wax will always stay the same. it is a physical change
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 burning of wax chemical or physical change?
it is a chemical change because it produces gases
Why burning of candle is a physical and chemical change?
CHEMICAL
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 balls of wax forming when melted wax is poured into ice water a chemical change?
No, it is a physical change.
