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.

Are reversible changes and physical changes the same?
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.
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
What is physically happening when water is dissolving a substance?
when we dissolve a substance then first of all there may occur physical change like shape,colour,temperature etc. these changes are called physical changes.
When the bread is cooked it turns to toast this change is not reversible describe a different non reversible change?
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
What chemical reactions are reversible?
All physical changes are reversible.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
Are most physical changes reversible or irreversible?
ghjt6henmkcv idiots
what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Are all physical change reversible?
No,they are not.
Can you think why are evaporation and boiling reversible changes?
They are reversible changes because they don't lead to the changes in chemical properties like boiling point, melting point, no. of electrons, etc. but changes the physical properties like mass, temperature, pressure, etc.
What is is a physical change?
A physical change is simply, a temporary change, which changes the physical characters of an object like its color, shape, size etc. It is a reversible change.
What are reversibile reactions?
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties
Which physical changes reversible?
reversible changes are substances that can be changed from one thing to another then back to the other thing again, like ice, when you heat ice it becomes a loquid, but if you put the ice back in the freezer then after a while it becomes a solid again, your welcome. :)
Is the freezing of mercury a reversible or irreversible physical change?
reversible. because you can melt it back to a liquid.
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
Is a bursting balloon a physical change?
no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
