Rusting - oxidation- corrosion.
This metal is iron.
Corrosion is the reverse of the change of state in your question. Rust is corroded metal [ iron, steel ].
Formation of rust is a type of chemical reaction called corrosion, Corrosion of an iron metal occurs when it reacts with either water or air to form a substance called hydrated iron oxide, also called rust.
rusting of iron . means when you put an iron object left open in moist air .... the moist air come into contact with the iron article and a brown flaky layer of iron oxide is formed on on the object. This is CORROSION of IRON .
Water droplet lands on the surface of a car with a scratch/dint
dry corrosion is taken place in the presence of gases whereas wet corrosion takes place in the presence of moisture in air
I think AIR is the most effective mean of corrosion and the most appealing example is the corrosion of iron when it comes in contact with air.

Eating away and eventual destruction of metals and alloys by chemical attack. The rusting of ordinary iron and steel is the most common form of corrosion. Rusting takes place in moist air, when the iron combines with oxygen and water to form a brown-orange deposit of rust (hydrated iron oxide). The rate of corrosion is increased where the atmosphere is polluted with sulphur dioxide. Salty road and air conditions accelerate the rusting of car bodies.
occurs when iron combines with oxygen in the air
Iron is oxidized and rusting appear.
Rusting - oxidation- corrosion.
iron
It is more resistant to corrosion.
Iron can react with water in the presence of air and form rust.
