It means that the substance can come back to its original phase.

What is an example of a physical change that can be reversed?
A reversible change is when something can turn back into its original shape for example when ice is melted it turns into a liquid but then you can freeze it into a solid again do the change is reversible because it can change back into its original starter which is the ice in this case. But if you make a cake it is not reversible because all of the mixture has mixed together and it turns into one object this is called a chemical change. Also a reversible change is a physical change! Hope this helped ;)
Is it true that a physical change and a chemical are exactly alike?
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
Are bubbles a physical property?
The bubbles themselves are physical. What caused them might have been a physical change or a chemical change; it's impossible to say without more information.
Is the melting of ice is a chemical or physical change why?
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
Is melting of wax reversible or irreversible change?
Yeah, definitely. Just wait.
Is physical reaction the same as physical change?
a physical reaction is non-reversible e.g. when you bake a cake or fry an egg. a physical reaction is reversible e.g. when you melt ice or chocolate. i did this in chemistry today, ^-^ (but did you mean a chemical reaction?)

What is an example of a physical change that can't be reversed?
Lets say I slapped you in the face. Your face would be red (possibly bleeding if I use my slapping gloves) and that would not be reversible (at least for the moment)
Is it correct to say the chemical changes are not reversible but physical changes are?
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.
Is removing nail polish chemical or physical change?
This is probably an example of the sort of ambiguity which is the reason 'physical' and 'chemical' changes tend not to be mentioned outside of early science education. The exact physical make-up of the solute (nail polish) is not changed, but chemical bonds are both broken and made in this process (various intermolecular bonds). The reaction is reversible, but then, all chemical reactions are reversible, but require extra energy put into the system to reduce the entropy. Probably the best approximation would be to say it is a physical change, since all/most of the molecules involved are structurally unchanged.
Why do you say that physical change has occurred?
WEA
What kind of change happens when a substance dissolves?
I want to say physical change
What does it mean to say that mass is conserved during a physical change?
There is one meaning when mass conserves during a physical change. This means that mass will stay the same after the change.
Is an egg turned into an omlette a physical or chemical change?
at a guess, my sister and i say physical

A physical change differs from a chemical change in that waste products are formed through chemical changes?
Not necessarily. This only happens in decomposition reactions, where energy reacts to break apart a compound. In, say, a synthesis reaction, sodium and chlorine combine, but don't leave a waste product. A physical change differs from a chemical change in that the product is the same substance, while in a chemical change it forms a/some different substance. Think about ripping a sheet of paper-is it still paper? If you burn the sheet of paper-is it still paper
