Answer 1

${\bf{{\underline {\underline{{Answer }}}}}}$

Physical changes may or may not be reversible changes. Like, turning of water into ice is an example of reversible changes but growth in height is an irreversible change.

Chemical changes are changes that occur in the chemical properties of the substance like its flammability, radioactivity, etc. All chemical changes are irreversible changes.

Answer 2

Answer:

Here's Your Answer

Explanation:

The melted ice cube may be refrozen, so melting is a reversible physical change. Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas),freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change.
