Is heating sucrose a physical or chemical change?
At first it is a physical reaction. If you keep heating it it will undergo a chemical change. In fact, once it melts you have altered its chemical makeup (melting by itself is a physical change but in sugar that also marks a chemical change). Heat more and it undergoes another chemical change and goes from clear to brown another chemical change takes places. Eventually you can drive off (almost) all but the carbon atoms.http://answers.yahoo.com/question/index?qid=20080906171221AAcGFPs
