physical changes are sometimes reversible
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.
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.
Temporary changes to a material are referred to as "physical changes." These changes alter the state or appearance of a material without affecting its chemical composition, such as melting, freezing, or dissolving. Unlike chemical changes, physical changes are usually reversible.
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
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.

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.

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.
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties

yes it is correct because chemical energy means you can't change something back like paper if you burned that paper you can't change it back but if you had that paper and you ripped it you can glue it back you can fix it that is physical energy when you can put something back together so yes you can say that.

No,it's a chemical change,because the petrol used can't reversible,also.A considerable amount of heat change is usually involved.
