Question

give three examples of physical changes. Explain whether each change is slow or fast, reversible or irreversible, and man-made or naturali​

Answer 1

Answer:

A change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some time, it transforms into ice. But as soon as you take it out of the freezer, it turns into water again. This is a reversible change.
