what is physical change and chemical change, what is galvanization and rusting
Answers
Explanation:
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.Galvanization or galvanizing (also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc.
Explanation:
physical change :- If there is a change in structure or physical appearance of a substance, then it is called as physical change
Chemical Change :- If there is a change in chemical composition of a substance, then it is called as chemical Change
Galvanization :- The Application Of Zinc Layer on the metal in order to protect them from rusting is called Galvanization
Rusting :- The Deterioration Of A Metal due to exposure to air or moisture or water is called rusting
