Which one is a chemical change -rusting of iron or melting of iron?
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
Which one is a chemical change rusting of iron or melting of iron?
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Is Melting an iron bar from a solid to a liquid is physical change buy why?
Yes, melting an iron bar from solid to liquid is a physical change because it involves a change in the state of matter without altering the chemical composition of the iron. The process of melting only affects the arrangement of the iron atoms, allowing them to move more freely in a liquid state, but the substance remains iron throughout. Thus, no new substances are formed during this transformation.
Why is melting of butter is a physical change whereas rusting of almirah is a chemical change?
Melting of butter is a physical change because it involves a change in state from solid to liquid without altering the chemical composition of the butter. Rusting of an almirah is a chemical change because it involves a reaction between iron in the almirah and oxygen in the air to form a new substance, iron oxide, which has different properties than the original iron material.
What type of physical change is heating iron to get liquid iron?
Melting, that's it
Is melting iron is a or physical change?
Melting of any element, including iron, is a physical change. Melting is just a transition between states of matter, from solid to liquid. The solid state of iron can be regained if the liquid iron is cooled; so this denotes a physical change. There is no change to the chemical composition of iron during melting.
Is melting iron physical change or physical property or chemical change or chemical property?
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.
Which one is a chemical change -rusting of iron or melting of iron?
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
What does it mean when there is physical change?
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.
Which one is a chemical change rusting of iron or melting of iron?
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.

Is an iron nail melting a chemical change?
No.
What an example of a physical change?
When it combines with Oxygen. Commonly called Rust.
Why is melting of butter is a physical change whereas rusting of almirah is a chemical change?
Melting of butter is a physical change because it involves a change in state from solid to liquid without altering the chemical composition of the butter. Rusting of an almirah is a chemical change because it involves a reaction between iron in the almirah and oxygen in the air to form a new substance, iron oxide, which has different properties than the original iron material.
What type of physical change is heating iron to get liquid iron?
Melting, that's it
Is the melting of iron a physical change?
Yes. Both, solid and liquid iron, are still iron.
Why is melting an iron nail an example of a physical change?
because when you melt an iron nail, It's still that iron nail, it's just in a different form. An example of a chemical change would be malting sugar, because When its melted, it's a completely different thing.
