Rust
Iron has the greatest density, followed by granite, water, and then dry air. Density is the mass per unit volume of a substance, and iron has a higher mass per unit volume compared to granite, water, and dry air.
Iron reacts with oxygen in air to form iron oxide, commonly known as rust. When iron reacts with water, it undergoes corrosion which is accelerated in the presence of oxygen. The reaction with water and oxygen produces hydrated iron oxide, also known as rust.
I don't know whether the main question is why iron rustsor why does it rust slowly but i will answer bothiron rusts in air because air contains oxygen and water.and for rusting to occur, you NEED both oxygen and water..why it rusts slowly because , although air has an abundance of oxygen (~30%) water does not (~1%) and that is why it rusts slowly. because there is lesser water in the air to react with the iron and oxygen.
When iron fillings are mixed with water, the iron fillings will sink to the bottom of the container due to their higher density compared to water. Since iron is not soluble in water, the iron fillings will remain as solid particles at the bottom of the container. Over time, the iron fillings may rust when exposed to oxygen in the air and moisture in the water, forming iron oxide.
Quantity of water in the air (or other medium surrounding the iron). Quantity of oxygen in the air (or other medium surrounding the iron). Additives to the iron during production. Surface area of the iron exposed. Chemicals in the air or other medium surrounding the iron that could catalyse the rusting process.
Air, iron and water will cause the iron to rust.
Iron oxide is typically formed by the reaction of iron with oxygen in the air, not water. Iron reacts with oxygen in the presence of air to form iron oxide. Water does not play a significant role in the formation of iron oxide in this context.

Seed plus powder is wood that grows but you have to water it Glass plus lightning is melted glass Vine plus lightning is growing a lot ice plus air equals snow
Iron can react with water in the presence of air and form rust.
sound travels the fastest in solids, then liquids, then gas. So it would travel through iron the fastest, then water, then air.
IRON OXIDE.......AKA RUST!
Iron rusts when it comes into contact with oxygen and water. The presence of these two elements, along with iron, is necessary for rust to form.
air
the modern iron has a small "shell" to hold the water in it now if its empty and is in water it may float from the air inside the iron
classical or chemical smog
Hydrogen plus yeast equals air bubbles?
