Chemical.
Can we get burnt paper back to its original form?
No it can't, because it would have undergone a chemical change, which is not easily reversible. so it is highly unlikely that it would. In addition, if burnt paper is touched, it would only crumple and turn to ash. Thus, your brilliant answer.

I would think it to be a Physical Change. Not chemical.
What does physical and chemical mean in science?
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
What does the word physical change mean?
A physical change means that only the appearance of the substance has changed. So if your tear up a piece of paper, its still paper so a physical change has taken place. If you heat or freeze water its only a change of state so its still a physical change. So long as the molecular or chemical structure of the atom/substance does not change it will always be a chemical change. H20 will always be H20.
