What is the different between physical change and reversible change?
Answers
Answer: Physical change is not a change in identity and can not be reversed. The physical change includes shape. Reversible change can be reversed. A reversible change is a chemical change where no new materials are made, and the original material can be brought back. Think of chocolate. If you melt it then it is a liquid but you can return it to its first state by letting it cool.
