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????
