The water and the air makes a chemical change to the nail to make it rust
Chemical change, oxygen binds with iron.
Corrosion is a chemical process.
Water and air in combination will rapidly cause iron to rust.
Well, if a nail was placed in the water, to prevent rust. Boiled water has no air and oil and water cannot mix so the oil stops any air getting in.
The water and the air makes a chemical change to the nail to make it rust
Because it is a chemical change. The iron(of the nail) is combined, chemically, with oxygen (air). 4Fe(s) + 3O2(g) == water==> 2Fe2O3(s) [rust]
It is a chemical change. Oxygen in the air (and sometimes water vapor) combines with the iron to form oxides. The rust is a new chemical with very different properties: it has little strength, can be washed away, and is no longer attracted to a magnet.
freezing water and evaporation is physical-only change in state of matter. rusting nail is chemical-alters composition of substance
Chemical change, oxygen binds with iron.
Bonds are formed between some of the iron atoms in the nail and oxygen atoms from the air.
Oxidization
A rusting nail is the oxidation of iron, in which the iron in the nail and the oxygen in the air react to form a new substance, iron oxide, with different properties from the iron and the oxygen.
Corrosion is a chemical process.
Water and air in combination will rapidly cause iron to rust.
Humidity ... damp air, water from rains.
