The best conditions for rusting to occur are when iron or steel is exposed to moisture (such as water or humidity) and oxygen. The presence of these elements initiates a chemical reaction that leads to the formation of rust. Additionally, exposure to salt or acidic substances can accelerate the rusting process.
For rusting to occur, iron must be exposed to oxygen and moisture in the air. This triggers a chemical reaction known as oxidation, which causes the iron to form iron oxide, or rust. Presence of an electrolyte such as salt can accelerate the rusting process.
Air can cause iron to rust through a process called oxidation, where oxygen reacts with iron to form iron oxide (rust). Moisture in the air accelerates this process by providing the necessary conditions for the reaction to occur.
Hydrogen peroxide does not directly cause metal to rust. Rusting occurs when metal is exposed to oxygen and water, which leads to the formation of iron oxide. While hydrogen peroxide can accelerate the rusting process by providing oxygen, it is not the primary cause of rust on metal.
Boiled water will not rust as rusting is a chemical reaction between iron and oxygen in the presence of water. Boiling water simply changes its state from liquid to gas (water vapor) and does not directly cause rusting.
Rusting requires conditions such as moisture and air (oxygen).
Rusting is an irreversible process.
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur

Yes, rusting is a very important problem for all iron structures.
Water and oxygen are needed.

Rust will not occur where it is dry and humid
Air and water.
Steel castings can prevent rusting depending on what the kind of steel. Carbon steel may cause rusting at a higher rate than stainless steel.
When rust forms on a nail the dark brown colour is the characteristics of rusting.
