Rust
No. Iron is naturally magnetic.
Melting of ice is an example of a physical change. In this process, ice changes from solid to liquid form without any change in its chemical composition.
An example of a chemical change is when iron rusts, forming iron oxide. A physical change example is when water freezes into ice.
Rust is an example of a chemical change. It occurs when iron reacts with oxygen to form iron oxide, changing the properties of the iron. This process cannot be easily reversed.
Melting an iron rod is a physical change
Physical change: bending. Chemical change: Rusting (oxidation). An example of both in one item: A wrought iron fence was heated and bent into a decorative pattern. After 20 years, the fence shows evidence of deep rusting, especially on decorative curves.
No, rusting of an iron fence is a chemical change. It involves a chemical reaction between iron, water, and oxygen in the air to form iron oxide (rust), which changes the composition of the iron. This is different from physical changes, which do not alter the chemical composition of a substance.
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.
A physical change is one where no new substance is produced. Melting is an example of a physical change. When you melt iron, you get liquid iron, it's still the same chemical substance. If you melt copper, you get liquid copper, not liquid iron.
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
Iron is a chemical element, not a "change" !
