Well, honey, a rusty nail is a chemical change. When that nail starts rusting, it's a whole chemical reaction going on between the iron in the nail and the oxygen in the air. So yeah, it's not just a little physical makeover, it's a full-blown chemical transformation.
The rusting of a nail is a chemical change. This is because the iron in the nail reacts with oxygen in the air to form iron oxide, which is the rust. This process involves a chemical reaction and results in a change in the composition of the nail.
Melting a nail is a physical change because only the state of matter is being altered, from solid to liquid, without changing the chemical composition of the nail. The nail can solidify again by cooling, showing that the change is reversible.
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 of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.

it is a Chemical change because before they are rusty they are perfect and they are a solid brown but over time they change colors because they are getting old H2O + air + metal = rust

hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
Heating is a physical change.
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
rusting of nails is a chemical reaction. iron combines with oxygen to form iron oxide which is rust. water/water vapour acts as a catalysthere.
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
Chemical change, oxygen binds with iron.
