Answer 1

Answer:

chemical change is different from physical change as

i m taking example.

as Ripening of fruits is an example of chemical change ..

Now the food has ripened so we cannt convert it to its original state i mean in raw fruit.

so its chemical change.

and in physical change...

e.g. rolling of chapati

we can change its shape or can change it in its original state in dough.

or another example...i.e.

mixing of iron nails in sand.

now we can seperate them by using hand or by using magnate. so we can make them to there original state.
