Explanation:
Detailed explanation-1: -Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar’s atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this chemical reaction in the form of smoke and black soot.
Detailed explanation-2: -On heating, sucrose decomposes to carbon and water. Water is lost as steam and only black ashes remains which contains carbon. Note: Caramelisation is browning of sugar.
