Rusting is actually a chemical change, not a physical chnage.
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Chemical changes take place on the molecular level
it is a chemical reaction because a new substance is formed when the wood rots
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
it is a physical change
physical change
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
physical change
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
first physical, second chemical
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Physical change
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
