Hey! Friend ...

Chemical change is permanent change whereas physical change is temporary change in which only physical state of same matter is changed without affecting its chemical composition. So, physical change can be reversed to its original state.

e. g. water changing in vapour which again can condense to form water, is physical change whereas burning of woods to form ashes is a chemical change, as we can't reverse it to form wood again.

Hope u like the answer ...

1) A Physical change doesn't change the chemical composition of a substance while a chemical change does.

2) Physical changes are reversible, Chemical changes are not

Examples:

Physical: Melting ice to liquid water

Chemical: Burning up paper
