the corrosion agents for iron are moisture and oxygen. Boiling the water removes all of the dissolved gases, including oxygen. The absence of oxygen in the water is maintained by the layer of oil. That prevents the iron from rusting.
Nails are made of steel which contains iron. What I am about to say goes for anything made of steel, not just nails.
When steel is produced in a steel mill, iron ore (rust) is converted into pure iron which is then alloyed with other elements (molybdenum, silicon, manganese, chromium, etc) to produce steel. Iron is the largest component in steel.
Iron is not stable from a thermodynamic perspective and it trys to revert back to its most stable form, iron oxide (rust). To prevent something from rusting, you must seek to interfere with the chemical oxidation of iron. For example, paint and other coatings block the action of moisture and oxygen on steel and thus rust is stopped.
Rust is Iron Oxide (Fe2o3). As there is oxygen in the air I would say that over time it will just oxidise and create rust. Ways of preventing rust would be to coat the iron in something, like painting it which will stop the oxygen getting to the iron to oxidise it.
because the minerals that caws things to rust are heated and change
Rust is caused by the oxidation of the metal in question, caused by contact with water. Rust can easily occur if the air is humid enough.
It rust as it comes into contact with oxygen and water.
This can be prevented by adding a layer of protection around the iron, such as paint or you can also use sacrificial protection.
Because nitrogen doesn't react with iron at room temperature and is not an oxidant.
A nail made out of just iron will rust really fast if it is exposed to oxygen. Nails available now, are galvanized nail which has a coating of copper metal on the surface of iron nail. This slows down process of rusting. Exposing a iron nail to water and other acidic environment along with oxygen, can make a nail rust pretty fast.
If an iron nail is exposed to air for a long time it reacts with the water vapour (moisture) and oxygen present in the atmosphere and a reddish-brown powdery coating is formed on it known as RUST (Fe2O3.xH2O) .
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
When the iron in a nail combines with oxygen it forms iron oxide. We call this rust.
No - the drying agent prevents the corrosion (rusting) of iron because the agent absorbs all the moisture and none if it will react with the iron nail thus no rust is made.
It depends on the quality of the nail. If it is painted it Amy take long to rust. In general it may take a month or so for the nail to rust.

If it is a new nail it will probably just turn dark. If it's a rusty nail it will become rust free.
no
no it will not rust a nail because the asdi in the lemon juice cleans the nail
Iron present in the nail oxidizes in oxygen to form the iron oxides
It either cleans the nail, or makes the nail have rust.
Well I did and experiment for 30 days with 7up and an iron nail and it did not rust.
Nitrogen is not necessary.
No, in order for iron to rust it must be exposed to oxygen. Since there is no oxygen in oil oxidation cannot occur.
Yes, Iron (Fe) will oxidise when exposed to oxygen
