Explanation:
MAKING DOUGH IS A PHYSICAL CHANGE BUT MAKING CHAPATTI IS A CHEMICAL CHANGE BECAUSE:
ONCE THE SHEET OF DOUGH IS MADE WE HAVE TO BURN IT,
SO ONCE IS GOES THROUGH BURNING PROCESS (AS WE KNOW ALL BURNING PROCESS IS CHEMICAL CHANGE) SO IT CAN'T BE TRANSFERRED TO DOUGH AGAIN, HENCE IT'S A CHEMICAL CHANGE
