What is the Difference Between a Physical Change and a Chemical Change?
Answer
The difference between physical change and chemical change is that while physical change basically involves a change in state of matter and energy, chemical change occurs at the molecular level. Chemical change brings about the creation of a new substance different from the original and is not reversible while in physical change, the substance remains the same though there may be a change in state of matter. Melting of ice is a physical change while resting of iron is a chemical change.
