In figure I, evaporation of water from sugar solution is a physical change because there is only change in state of matter from liquid (sugar solution) to solid state (crystals of sugar). In figure II, when sugar is heated, it turns black due to the formation of a new substance and it cannot be reversed. Therefore, it is a chemical change.
