A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
examples of physical change are ice,water,chocolate,liquid,
A Bunsen burner is an object: it is not a process of any kind.
Irreversible
physical change is reversible because you can undo it for example: if you fold a paper you unfold the paper. chemical chang is irreversible because if you make somthing together you could not seperate them.
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
A mixture of salt and sand is an example of a physical change since the process is reversible.
Examples of reversible matter include water (liquid to solid state), melting ice (solid to liquid), and evaporating alcohol (liquid to gas). These examples involve phase changes where the matter can easily transition back and forth between states without undergoing any permanent chemical changes.
All physical changes are reversible.
no
No, it is not.
Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.
chemical reactions are irreversible but physical changes are reversible
Reversible states: solid, liquid, gas
A physical change is a change in a substance that does not alter its chemical composition. Examples of physical changes include changes in state (solid, liquid, gas), changes in shape, size, or texture. These changes are reversible.
