Yes, it can be brought back to solid by cooling. Because butter has only changed its state, which is a type of physical change. But some substances solids change their chemical composition instead of changing to liquid form, like Sugar. Sugar on heating turns red then black. Sugar cannot be brought back to its white solid form by cooling.

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.
Is melting paper clip a physical or chemical change?
Melting a paper clip is a physical change because it does not alter the chemical composition of the paper clip. The paper clip simply changes from a solid state to a liquid state and can be reversed by cooling it back to a solid.
Why is burning butter a chemical change but melting is not?
Heating is an increase in energy in a substance. Heat is merely the measure of excitation of atoms or molecules, and as such heating a substance does not usually change anything chemically, unless you have a very unstable chemical (E.g. Argon Fluoride doesn't function above -233 Celsius.
Is melting a physical or chemical property of sulfur?
Physical - because melting isn't a change in it's chemical structure, it has just changed its physical state of matter. Generally (but not always) physical changes are reversible (can be taken back) but chemical ones cannot be reversed easily.
Is the melting point of butter a physical or chemical property?
The physical properties of butter include soft and in some cases, liquid. This depends on what type of butter it is.
Give one example of physical change that could be easily reversed?
Change of state from a liquid to a solid and back again.
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.
Is the burning of leaves or melting of butter a physical reaction?
The burning of leaves is a chemical reaction. The way we can tell is because after the leaves are burned, they cannot go back to the way they were. Butter melting is a physical reaction because it does not change the molecules, and the butter has the ability to go back to it's original state.
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.
What is a phyisical change?
A physical change is a change in the form or appearance of a substance that does not alter its chemical composition. Examples include changes in state (e.g., melting, freezing) or changes in shape or size.
Is melting paper clip a physical or chemical change?
Melting a paper clip is a physical change because it does not alter the chemical composition of the paper clip. The paper clip simply changes from a solid state to a liquid state and can be reversed by cooling it back to a solid.
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 ;)
Is melting butter for popcorn a phiscal change?
Physical because once you melt it you can put it in a fridge and it will go back to the original state from before you melted it
Is Warming butter an irreversible change?
Yes as once melted you cannot get the same substance back. Think about putting butter onto your toast it changes its texture completely! thanks for that.... it is irreversible because anything that is cooked;it candt be reversed(:
Why is burning butter a chemical change but melting is not?

Is welding pieces of metal is chemical change?
not it can always be changed back to its original shape. but if you burn metal which i dont consider doing it is a chemical change. like melting butter and burning butter. burning is chemical, melting can be cooled again into its original form.
Is melting a physical or chemical property of sulfur?
Physical - because melting isn't a change in it's chemical structure, it has just changed its physical state of matter. Generally (but not always) physical changes are reversible (can be taken back) but chemical ones cannot be reversed easily.
