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 ;)
Are boiling and melting chemical or physical changes?
It's a physical change. You can turn it back to its original state, and the substance's identity is the same. (ex: water vapor and ice are still H2O)
Is bolling water a chemical change?
No, it's a physical change, for you can change steam back to its original state, water
Is mealting an example of physical or chemical change?
it is a physical change most of the times because you can get i back into its original form. for ice, or plastic... its physical. but for styrofoam, its a chemical change because you cant get it back.
Is baking cake a physical change or chemical change?
Baking a cake involves both physical and chemical changes. Physical changes occur when the cake batter changes form (such as turning from a liquid to a solid). Chemical changes occur when the ingredients react with each other during baking, leading to the formation of new substances that give the cake its flavor and texture.
What is the effect of physical changes?
Physical changes do not change the properties of the substance. You can get back the original state of the substance in most cases by reversing the physical process.
When platinum is heated then cooled to its original state is a physical change?
Yes, heating platinum and cooling it back to its original state is a physical change. This process involves a change in the state of matter (from solid to liquid and back to solid) without altering the chemical composition of the platinum.
What is a non reversible change?
A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back

What can you change back from a physical change?
A physical can be changed back to it's original form. For example, if you freeze water, it turns into ice. However, if that ice melts, it turns back into it's original form: water.
What changes shape but can change back to its original form?
A rubber band can be stretched to change shape but can go back to its original form when released.

Why are chemical changes different from physical changes?
Chemical changes cannot be changed back to how they originally whereas physical changes is only the appearance has changed and can be changed back to their original state e.g chocolate (cam be melted and then hardened)
