Can something be a physical and chemical change at the same time? Solution :
Yes, in some cases the physical and the chemical changes can occur together
. One such example is the burning of candle. The wax present in the candle changes to liquid state. This means that the change is of physical nature.
Can physical and chemical change happen at the same time?
