Of course why not in the case of a candle we experience two changes physical change and chemical change in that physical change the solid wax melts to form molten wax this is a physical change but in a chemical change the thread of the candle burns to produce new substance that is burning and the residue is left in the atmosphere.
->PHYSICAL CHANGE IS A CHANGE WHEN THE CHANGE CAN BE REVERSED LIKE THE MOLTEN WAX CAN BE CERTIFIED AGAIN AND SOLID WAX CAN AGAIN BE MOLTEN.
->IN A CHEMICAL CHANGE THE CHANGE CANNOT BE REVERSED BUT A NEW SUBSTANCE IS FORMED LIKE THE RESIDUE PRODUCED WHILE BURNING.
Hope this would be clear to you if not please contact me at the comment section and don't forget to mark as the brainliest.
