Answer:
- Ships get rusted because sea have the best atmospheric conditions of rusting that is because of salt present in it. Salt present in sea water reacts with iron and it stars rusting.
The lower parts of boats and ship which are made of iron, but they are always dipped in water. How is it that they do not rust so easily and quickly?

They certainly do rust, and very quickly indeed. To check this, take a few nails from the hardware store and put them in a glass of tapwater. If you live near the sea, do another with seawater. Check next morning - within a day or so the nails will have rusted, the ones in seawater much quicker than the ones in fresh. All metals dissolve in seawater, even gold.
Ship’s hulls are not made of iron, they are made of steel (as are your nails from the hardware store), and it rusts just the same. For this reason millions of dollars are spent on cleaning, preparing and painting a ship’s hull, especially at and below the waterline where most corrosion occurs. It’s a never-ending job, and to help combat it, special epoxy paints are used on the underwater sections, along with sacrificial anodes to help protect the steel hull where the coating has been removed or damaged. On top of that goes antifouling to try and keep the hull free from marine infestation. The insides of cargo holds and especially ballast tanks are also subject to corrosion and have to be treated, coated and looked after to prolong the life of the ship and avoid expensive steel-renewals.
A shipowner is well advised to spend these millions, as advanced corrosion on his ship hull and internal spaces could send it to the scrappers rather early in its career. There was a businessman who had ships built with no paint at all, intending them to have paid for themselves in 3 years, and to scrap them at 5. Don’t remember how that particular idea got on, but no one has done it since, unsurprisingly. Ships are an expensive investment, and you need to look after them unless you are buying them for one charter before sending them up the beach.
Why do iron ships not get rusted after its part remain underwater?
Why do sea ships and submarines not get rusted easily?
Why ships are rusted fastly in water?
Can iron be rusted when it is completely dipped in water?
Can a piece of iron rust without water?
Navy ships are usually built of thicker steel, such that the weakening process of external and internal rusting becomes less significant. However, even sea air can induce deterioration. The freeboard of the ship is painted frequently by it’s crew. When possible to ship travels in fresh water to kill sea organisms that attach to the hull, however the dead shells still tend to slow the ship’s movement. If and when the ship requires drydocking for repairs, the opportunity allows for removal of animal remains and inspection of the underwater paint condition, and possibly sanding and repainting.
2. (A) The ribbon burns with a bright white light. Intense heat is also produced in this reaction. Here, when magnesium burns, it reacts with the oxygen found in air to form a powdery ash called magnesium oxide.
Mg + O = MgO
(B) Magnesium Oxide also reacts with water to produce the. corresponding hydroxide, magnesium hydroxide.
Mg + 2H2O = Mg (OH)2 + H2. MgO + H2O = Mg (OH)2
