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.
What else can I help you with?
Are all physical changes are reversible changes?
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 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.
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.
Can a physical change always be reversed?
Yes, physical changes can usually be reversed because the substance's molecular structure remains the same. For example, melting ice into water and then refreezing it back into ice is a reversible physical change.
What chemical reactions are reversible?
All physical changes are reversible.
Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
Are all physical changes are reversible changes?
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.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
What is the meaning of physical changes?
Is a changes which is reversible no new substance is made.
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.
Are most physical changes reversible or irreversible?

Is an example of a physical change?
Processes that are reversible are physical changes. An example is the melting of ice.
Are physical and chemical changes simply reversible and non reversible changes?
Chemical changes create new substances and cannot be reversed.Burning paperLighting a matchMixing sugar and waterPhysical changes do not create new substances and can be reversed.Crushing a canTearing paperChopping wood
Are physical changes reversable?
Physical changes can be reversible or irreversible depending on the nature of the change. For example, melting ice is reversible as it can be frozen again, while cutting a piece of paper into smaller pieces is irreversible.
Why are most physical changes reversable?
Most physical changes are reversible because they involve only changes in the physical state or appearance of a substance, rather than its chemical composition. Reversible changes usually involve processes like melting, freezing, dissolving, or changes in shape, which can be easily reversed by applying the appropriate conditions to change the substance back to its original state.
What Is the difference between physical changes and chemical change?
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.
