it is a physical change
no because all you are doing is changing the shape and form
Carving pumpkin physical change or chemical change
Making plastic container is a chemical change.
it is a physical change most of the times because you can get i back into its original form. for ice, or plastic... its physical. but for styrofoam, its a chemical change because you cant get it back.
Yes, burning (oxidation) is chemical change.

Yes. Carving wood is a physical change because you are changing its appearance without changing what its made of.

It is a physical change.
physical change
Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
I think that its a chemical change because you cant put its back into what its was before you carved it .
chemical
Carving a stone or molding a dough
Making plastic container is a chemical change.
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.
no its just physical change
