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 ;)
What else can I help you with?
Give one example of physical change that could be easily reversed?
Change of state from a liquid to a solid and back again.
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.
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
Is a given change a chemical or a physical change?
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
What are example of a physical change that can be reversed and an example of a physical change that cannot be reversed?
An example of a physical change that can be reversed is melting ice into water; this can be reversed by freezing the water back into ice. An example of a physical change that cannot be reversed is breaking a glass; once the glass is shattered, it cannot be returned to its original form.

Change of state from a liquid to a solid and back again.
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
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.
How is sour milk a chemical change?
When milk turns sour, it is a chemical change because the bacteria in the milk ferment the lactose sugar into lactic acid, which changes the composition of the milk. This process cannot be easily reversed, making it a chemical change rather than a physical one.
Evaporation a physical change?
Yes, because it can be reversed by condensation. Physical change = Reversible Chemical change = Irreversible

Is molded clay physical or chemical change?
physical, because it can be easily reversed
Why can a physical change be easily reversed?
it can be easily reversed because nothing new is produced. it is the same particles but just rearranged. it is just a change in size, shape or state ***IT IS REVERSIBLE*** but what physical change is not easy to reverse?
What is physical change in matter?
A physical change is a change to a substance/object which can be easily reversed, and no new substance is formed from it (as opposed to chemical change). The state of matter is usually changed, for example, turning from a solid to a liquid. e.g. ice cube melting
Is a given change a chemical or a physical change?
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
Is rust an example of a chemical change or a physical change?
rusting is oxidation, so it is definitely a chemical change
