For my year 7 homework i have had to write a poster about pyhsical and chemical changes when a candle is alight. We have had to use certain vocabulary and one is evaporation. I know what this term means but don't know what evaporates when a candle is alight? Can someone please tell me what evaporates when a candle is alight and burning??????? Is it the gas made from the burning wick????
Answered by bobpursley
doesn't the wax melt, and then the heated liquid vaporizes, thence the gas burns in the atmosphere?
Answered by Bob
The candle burning breaks apart the hydrocarbons comprising the candle and forms water which it immediately evaporates.
