When a candle is lit,and the wax vaporises, is it a physical or chemical change?

Question

Also, when the wax burns, is it a physical or chemical change?

Answer 1

A physical change because it changes from solid to liquid to gas.

Answer 2

Wax vaporising is a physical change. Burning is a chemical change.

Answer 3

I say both.

The consumation of the wax by fire is chemical change of fuel into energy.

The wax changes physically from solid to liquid to gas during the interim as well.

Answer 4

When a substance changes state (solid to liquid, for example) it is a physical change,

Once the structure of the substance changes (for example, burning) it is a chemical change,

Answer 5

i might want to say actual because we merely discovered about that(i'm in sixth grade I actually have the intelligence of an man or woman.)also because a chemical change is at the same time as 2 or extra substance come jointly to create a clean substance. A Phisical change is at the same time as the item continues to be an same,notwithstanding the residences change.

Answer 6

Physical.

Answer 7

you have some O(oxygen) turned into CO2
that is chenical
you have wax melt that is physical
you have wax burnt that is chemical
and finally there is the candles cotton inside wax this is chemical

Answer 8

A change in state is always physical change

Answer 9

Both, the wax melts and then is use as fuel and therefore is oxised (In this case is it most likely to be turned into carbon dioxide)

Answer 10

yup it is physical, it can be changed back into liquid once the vapour condenses. a chemical change is irreversible
