Iron must be in contact with oxygen, water (and dissolved ions) to rust. So if it was in boiled water there would be no oxygen present and as long as no oxygen was allowed to dissolve back into the water, for example if a layer of oil was on top of the water, then the iron nail would not rust.
Yes, Iron rusts very well with water, even boiled water.
Explain how the following prevent rusting
a) freshly boiled water
b) cooking oil
Iron needs water and oxygen to rust. If water was boiled, it removes dissolved gases, including oxygen so it would not rust.
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.
It rusts faster in salt water.
Humidity ... damp air, water from rains.
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
It speeds up the oxidation process, or in other words, it speeds up how fast oxygen molecules attach themselves to the iron to create iron oxide (rust).
It will rust a bit, but not much.
This really depends on the concentration of impurities in water. More the impurities, faster it will rust the iron nail. To reduce rusting of any iron the best way is to paint the nail.
Nothing will happen to iron in oil. You may be thinking of the standard rusting experiment where one of the tubes contains an iron nail in boiled water sealed with oil. The purpose of this tube is to show that iron needs oxygen to rust. The boiled water does not contain dissolved oxygen and the oil prevents more from entering from the air.
Yes, rust happens to iron nail though it is kept in distilled water.
Water and air in combination will rapidly cause iron to rust.
A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.
The Oxygen in the water reacts with the iron in the nail, making Ferrous Oxide
water and iron. Creating iron oxide aka rust.
An iron nail will rust slowly in distilled water when that water has dissolved oxygen. If you get rid of the oxygen by boiling and keep it from getting back in then the iron nail will not rust at all.
coke will make it rust faster
I'm not so good at science but I think The Oxygen from the water (H20) oxidises the iron and makes iron oxide, which is rust.
the exposure of water or moisture to the iron nail will convert the element to fe+3
