chemical change
Chemical
Chemical, the black spots are the compound silver sulfide.
Baking a pie is a chemical change because the cells of the ingredients are broken down when they get hot. You can see this when the crust becomes firm or the fruit in a pie becomes soft.
Potassium is an abundant chemical element: cca, 2,5 % in the Earth crust.
Aluminium, is the commonest metal in Earth's crust and the third most plentiful chemical element on our planet
Feldspar is a group of minerals making up almost 60 percent of the Earth's crust. The chemical formula is a very odd sequence, listed as KAlSi3O8-NaAlSi3O8-CaAl2Si2O8. This sequence repeats as a unit.

It is both- the browning of the crust is a chemical change as well as any other browning. If the filling simply boils and loses moisture ,that is a physical change.
Crushing the graham crackers is a physical change, not chemical. *Chemical reactions and chemical changes are the same thing.
no !
Weathering, chemical change, and mechanical change. I hope i could help.

The outermost chemical layer is the crust. The outermost physical layer is the lithosphere (the crust plus the attached uppermost mantle).
You would need to know if the silver underwent change that left the silver as it was originally, (in this case, having a black substance attach to it) or a change that made the silver into a new substance (like tarnishing). If the silver is still the same before and after the change, it was a physical change. If the substance is changed into a different substance after the change, it is a chemical change.
Pies do have starch. It is because of their crusts. The crust has flour, which is a starchy ingredient.
by the chemical composition is: the crust, the mantle (upper mantle and mantle), and the core. (you can put inner or outer) by the physical property is: lithosphere, asthenosphere, outer core, inner core. hope i helped
