Neither.
The rusting of iron is a chemical change because the iron reacts with oxygen in the air to form iron oxide. This process cannot be reversed by physical means and results in a new substance being formed.
A simple mixing is a physical process.
A simple mixing is a physical process.
No, rusting of iron is a chemical change. It occurs when iron comes in contact with oxygen and water, leading to the formation of iron oxide (rust). This process involves a chemical reaction, where the iron atoms combine with oxygen atoms to form a new substance.
Rusting is a chemical process, an oxidation reaction.
Adding water (which is not a reactant) is a physical process.
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
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).
Hammering hot iron into a sheet is a physical change. The process involves changing the shape and size of the iron without altering its chemical composition. The atoms in the iron remain the same, only the physical properties are altered.
The magnetism of a strip of iron is primarily a physical change. When iron is magnetized, the alignment of its internal magnetic domains changes, allowing it to exhibit magnetic properties. This process does not alter the chemical composition of the iron; thus, it remains a physical transformation rather than a chemical one.
Corrosion is a chemical process.
