physical. All you're doing is changing the temperature of it, not changing what it is.
Partly physical, partly chemical. Melted butter has different chemical properties than solid butter. The melting process, as with chocolate, is not reversible. Proteins in the butter can become denatured, and isomerization of lipids to trans fats occurs. Phase change is a common example of physical change, but chemical change also occurs in this case.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
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.
Cooking involve many chemical processes but also some physical processes as evaporation or melting.
Melting of butter is a physical change.

A physical change
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)

Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
Melting of butter is a physical change, a change of phase; but the brown color, at high temperature, is an indication of thermal decomposition - this ia a chemical change (change of composition).
No, its a chemical change because even after its melted, it's still butter
