A chemical change.
a physical property cause wax melting isn't a chemical change. It's a physical change :)
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
Changing from a solid to a liquid is a physical change. The chemical composition of the wax does not change.
Burning wax is a chemical change. If you are burning something, it will always be a chemical change.
This is a chemical process.
New substances are being formed and old ones consumed, so this is a chemical change.The melting of the candle wax is a physical change. The burning of the wick is a chemical change.When a candle burns, both a physical and chemical change takes place. The melting of the wax is the physical change, whereas the chemical change is the combustion of the wax and the wick.
no, physical change
This is a physical change.
Both. The wax melts which is a physical change and then the carbon atoms in the wax combine with oxygen which is a chemical change.
Melting is a physical change, not a chemical change.
when wax of the candle burns it is a physical change but when wick of the candle burns it is a chemical chang
Burning is a chemical change.
Physical change. No atomic interactions in melting wax which is only a change of state.
A physical change- it can be undone. Melted wax can cool and solidify.
Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
Dissolving of NaCl and melting of wax are physical changes.
Melting a candle wax is a physical change because, even though if the wax is already melted, it is still a wax.
It is a physical change, with a little chemical change due to action of the heat.
It is physical change. It is a physical property. There is no change in the composition of the was as it becomes liquid.
no because the wax will always stay the same. it is a physical change
it is a chemical change because it produces gases
