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 ;)
One example of a non-reversible physical change for water is freezing. When water freezes, it changes from a liquid to a solid state, and this change cannot be easily reversed simply by raising the temperature back to its original state.
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
Evaporation is a physical change: a change of state that is 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.
Reversible
Processes that are reversible are physical changes. An example is the melting of ice.
No, a decaying compost pile is not an example of a physical change. The process of composting results in a different physical appearance or state -- which is physical change -- but it is not reversible and necessitates a change in structure -- which is chemical change.
A physical change is reversible.
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.

Nearly, a physical change creates a substance and this is reversible. For example, ice-water. Water-steam. These are all reversible. A chemical change is irreversible. For example, baking a cake; you cannot get the original ingredients back again.
No,they are not.
A mixture of salt and sand is an example of a physical change since the process is reversible.
