Oxygen.
Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
Oxygen is the gas that causes iron to rust. When iron is in contact with oxygen and water, it forms iron oxide (rust) as a result of a chemical reaction. Candles burn due to the combustion of wax, which releases carbon dioxide and water vapor.
The products from the reaction of water and an active metal typically include hydrogen gas and a metal hydroxide. For example, when sodium reacts with water, it forms sodium hydroxide and hydrogen gas.
Water can exist in three main forms: solid (ice), liquid (water), and gas (water vapor). These different forms are dependent on the temperature and pressure of the surroundings.
Solid, liquid, gas. (Ice, water and steam)
The oxygen gas in rust comes from the oxidation of iron when it reacts with oxygen in the air or water. This reaction forms iron oxide, commonly known as rust, and releases oxygen gas as a byproduct.

Rust is a chemical compound known as iron oxide that forms when iron reacts with oxygen in the presence of water or moisture. Iron is a metallic element, while oxygen is a gas. Rust is a reddish-brown flaky material that forms on the surface of iron when it corrodes due to oxidation.

When water is heated and turns into a gas, it forms water vapor.

Condensation
Rust is most of all 'metal oxide' which is chemically formed by reaction of certain metals (not all) with oxygen (gas, 20% in air)
