What kind of change causes iron to rust is a physical change?
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).
Is the formation of stalagmites a physical or chemical change?
It is a physical change.
Is formation of water is a physical or chemical change?
physical change
Which of the following processes involves both physical and chemical changes?
Rusting of iron involves both physical and chemical changes. The physical change involves the formation of iron oxide on the surface of iron, while the chemical change involves the reaction of iron with oxygen in the presence of water to form iron oxide.
Is formation of stalagmites in a cave a physical or chemical change?
it is physical
What evidence of chemical change occur in iron rust?
The evidence of chemical reaction in the rusting of an iron nail is a color change. This is due to the formation of iron oxide, which is the reaction between iron and oxygen.
Is the formation of gas a chemical change or physical change?
Chemical change
Is rusting of an iron fence a physical change?
No, it is a chemical change (conversion to iron oxide)
Is getting iron from iron III oxide a chemical or physical change?
It is a chemical change.
Is Melting coin being heated and turn black this is used as a test for metal a chemical or a physical change?
The melting of a coin due to heat is a physical change as it alters the physical state of the coin from solid to liquid without changing its chemical composition. The black color that appears is likely due to the formation of an oxide layer on the surface of the coin, also a physical change.
What is type of change that doesnt involve the formation of a new kind of matter?
physical change
Is the heating of iron III oxide for sometime a physical or chemical change?
Just heating the metal would be a physical change, as you would only have a warmer iron III oxide. However, if the heat caused a reaction, it would then be a chemical change.
