There isn't really any such thing as an irreversible change, just changes that are so difficult they are unlikely to happen. It's a chemical change, because rust is a different substance from iron. If you put rust into a very hot furnace with carbon you can reduce it back to iron.
Yes, this change is reversible.
Reversible: the light goes on, producing illumination; it goes off and it's as dark as it was. Irreversible: light causes a plant to grow which is not immediately reversed when the light is turned off
Burning is an irreversible change.

irreversible change is called a physical change.
As I have learned, it is an irreversible change, so no its not a reversible change.
Rain is a natural phenomena and is not reversible.
Rusting is an irreversible change because it involves a chemical reaction between iron and oxygen, resulting in the formation of iron oxide (rust). Once iron has rusted, it cannot be converted back to its original metallic form without undergoing a complex chemical process. The properties of rust are different from those of iron, further confirming that rusting cannot simply be reversed.
A cake mixture is a combination of various ingredients. Once mixed, it would be impossible to separate the ingredients - which makes it irreversible.
reversible. because you can melt it back to a liquid.
it can't be changed,i.e.,irreversible change...
