Answer:
Explanation:
Fire is hot because thermal energy (heat) is released when chemical bonds are broken and formed during a combustion reaction. Combustion turns fuel and oxygen into carbon dioxide and water. ... Both light and heat are released as energy. Flames are visible evidence of this energy.
sugar is formed from two simple sugars: glucose and fructose. All sugars are sweet because they contain OH groups with a particular orientation that can interact with the taste receptor for sweetness in our tongues.
