The process of iron rusting is a chemical change, not a physical change. It involves a chemical reaction between the iron, oxygen, and water in the environment, resulting in the formation of iron oxide (rust).
No, a physical change does not change an object into a different kind of matter. It only alters the form or appearance of the substance, such as size, shape, or state (solid, liquid, gas), without changing its chemical composition.
An unbalanced force acting on an object causes it to change its motion. This force can come from interactions like pushing, pulling, gravity, or friction. The change in motion can be a change in speed, direction, or both.
A physical change is any kind of change that occurs in matter without changing its chemical composition. Examples of physical changes include melting, vaporization, sublimation, a piece of glass shattered into pieces, shredding paper.
When a liquid changes into a gas, it undergoes a physical change known as vaporization or evaporation. This change involves the molecules in the liquid gaining enough energy to overcome the intermolecular forces holding them together and escape into the gas phase.
Condensation is the change from gas to liquid.
physical weathering
It depends if the change is physical or chemical. If it is a physical change, the wood or iron never really changed, just it's physical appearance. If the change is chemical then the wood or iron supposedly can't change back to it's original substance or matter.
It is a physical process. Not really a change of any kind.

An orange is a physical object and is not any kind of "change"!
An 'iceberg' is no kind of change, but the melting and forming is a physical change.
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
The chemical that causes rusting of iron is oxygen in the presence of water. This process is known as oxidation, where iron reacts with oxygen to form iron oxide (rust) in the presence of moisture.
