no
No, the formation of balls of wax when melted wax is poured into ice water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of the substance, which is not occurring in this case.
Melted wax is a physical change, not a chemical change. When wax melts, its state changes from solid to liquid without any change in its chemical composition. Chemical properties refer to how a substance interacts with other substances in a chemical reaction, and melting wax does not alter its chemical properties.
Burning wax is a chemical change. If you are burning something, it will always be a chemical change.
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
no because the wax will always stay the same. it is a physical change
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.
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.
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
it is a chemical change because it produces gases
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
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.
NO... physical
