Is heating sugar physical or chemical change?
It is a physical change and only becomes a chemical change if the sugar is burnt.
If you add sugar to lemonade is it a chemical change or a physical change?
Physical. The sugar is only held in suspension. The basic reasoning behind this is that you have to stir the sugar in to get it mixed into the lemonade. A chemical change would have been generated just by mixing the chemicals together and given some type of reaction.(Heat, smoke, light, etc) You don't get a "bang" by adding sugar to lemonade. :-)
