is magnetizing a nail a chemical change
People also ask
Is magnetization of an iron nail a physical or chemical change?
Explain that magnetization of an iron nail is a physical change? It is a rearrangement of the atoms already present, without changing their form chemically. A chemical change is the result of a change in the atomic structure of an atom – a gain or loss of electrons.
Is magnetization a chemical change or physical change?
Explanation: A chemical change is the result of a change in the atomic structure of an atom – a gain or loss of electrons. Magnetization simply aligns the existing iron atoms in a certain way due the effect of a magnetic field on their dipole characteristics. It does not change the chemical composition or structure of the iron atoms in any way.
Is crystallization a physical or chemical change?
Crystallization is a physical change. What are physical and chemical changes? A chemical transition is the result of a chemical reaction, and a physical change occurs where the structure of matter changes but not the chemical identity. Examples of chemical transformations include fire, frying, rusting, and rotting.
What is the difference between physical and chemical change?
Also, no new substance is formed in the above physical change. What is a Chemical Change? A change in which one or more new substances are formed is known as chemical change. For Example, when the iron is exposed to air and moisture, rust formation takes place. Rust is nothing but Iron Oxide; a new substance formed out of the reaction.
