no, you cannot get cheese back to cheese when melted
a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
chemical change is easily reversible whilst physical is not reversible
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
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.
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
yes it is. because you can freeze it and melt it
Melting is a reversible change of state, whereas a chemical change is irreversible.
metal melting is a reversible change because as soon as you make the melted metal and freeze it, it might not come back the way it was but at least it is still the same metal material that you had.
It is changing from a solid to a liquid, which is a physical change.
Yes, the icecream can be frozen again.
Freezing water is reversible because you can get it back to its original state by melting it - it turns back into water.
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
No, a lava lamp is not a reversible change. The melting and mixing of the wax and oil inside the lamp is a physical change that cannot be easily reversed to its original state.
Processes that are reversible are physical changes. An example is the melting of ice.
A reversible change is where like if you had some ice, you could melt and then change it back to ice again making it a reversible. An irreversible change is something that can't be reversed, like burning food, as you cannot unburn it. Hope I helped!
The melting of ice in a drink is a physical change because the chemical composition of the ice (water) remains the same. The change is reversible since the ice can refreeze if cooled.
