If we have some candle wax and we make a candle doll from it, then it is called a physical change.

A physical change is a change, in which no new compound is formed. Only the physical properties of matter change such as size and shape. Usually, it is a reversible type of change. Here also, we can make a candle doll from candle wax and later we can reverse it back to its original shape. Thus, it is a physical (reversible) change.
