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.
Yes. Butter is a solid, and it melts to a liquid.
physical. All you're doing is changing the temperature of it, not changing what it is.
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.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
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.
Melting is a physical change.
No, it is a change-of-state.
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.)
Physical.
It is not chemical change ,it is a physical change
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
physical.
physical change
No, its a chemical change because even after its melted, it's still butter
During melting the chemical structure is not changed; but rusting involve chemical rreactions.
