Yes. Carving wood is a physical change because you are changing its appearance without changing what its made of.
Smashing a pumpkin is a physical change.
I think that its a chemical change because you cant put its back into what its was before you carved it .
a chemical change involves the formation of a new compound, whereas a physical change just changes from one form/state to another. An example is boiling water changes it from a liquid to a gas but it's still water(H2O) so thats a physical change. However somthing like metal rusting involves the addition of oxygen so iron rusting would go from Fe to FeO2 which is a new substance, hence a chemical change. Carving wood (though not an element as in this example) causes a physical change but not a chemical change.

Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
This process involve chemical reactions but also physical changes.
no because all you are doing is changing the shape and form

It is a physical change, because you're giving the wood a new shape.
