Because of Iron Oxide
because of it's oxidation
beacause of the gravity of the earth and the satilliate .
No.It is oxygen that is the gas needed to turn metallic iron into iron oxide (otherwise known as rust). Water and some form of electrolyte are also required to perform the electrochemical reaction.
it will turn to rust.
Rust itself doesn't have a distinct smell, but it is often associated with a metallic, earthy odor due to the iron oxide that forms when iron oxidizes. This smell can be influenced by the presence of moisture or other materials, such as decaying organic matter nearby. In some cases, rust may also carry a faint scent reminiscent of stale or damp metal. Overall, the odor of rust is subtle and might not be easily recognizable.
A fallen [dead] tree does not rust. Rust is a term specifically applying to the oxidation of Iron and some compounds of Iron. The breakdown [biodecompositon] of trees and other plant materials is accomplished by the action of living microbial "critters" that eat and digest the plant materials resulting in different compounds.
Depends on the type of film. Usually a polyester substrate with a UV inhibitor. Some films contain metallic elements. And some are made of ceramic materials.
Rust, Iron is quite reactive in that manner, so it would rust
No, rust is not an insulator. Rust is a form of iron oxide that is a poor conductor of electricity, but it is not a true insulator. It can still conduct electricity to some extent due to the presence of iron in its composition.
With the exception of iron , no metals rust. Rust is the oxide of iron. However, most metals do form oxides. Notably Gold and Platinum do not readily form oxides.
Iron in the form of steel, aluminum pure, copper for some items, many other metals in trace amounts (such as chromium and nickel in stainless steel, titanium coatings for a range of materials).
Most likely some other object has dripped rust onto the copper, which can be removed. Copper does not rust, but it does form a green patina over time.
