Butter can have a change of state because it can go from being a solid to a liquid if you melt it.
Butter is a change of state
Yes
Ooo=
No, it is a change-of-state.
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.)
No, because you are not changing the state of matter. All that you are doing is just a physical change, because the butter is not changing at all.
When butter hardens, it is a physical change. The change in state from liquid to solid is a physical transformation, meaning that the molecules rearrange themselves without any change in their chemical composition.
Making butter involves the materials in a mixture to be separated. This makes the process of making butter a type of physical change.
Melting butter is a physical change. Although the state of matter changes(solid into liquid), it is still the some substance.
Yes--it is only changing state of matter. If it had changes in properites, then it would be a chemical change.
Butter can be melted.
Melting of butter is a physical change.
Butter is the physical state of being a solid, like a brick. Rusting is a physical change where the metal atoms of iron on the metal object combine with the atoms of another element, oxygen. This creates a new molecule, rust, or oxygenated iron.
Yes--it is only changing state of matter. If it had changes in properites, then it would be a chemical change.
Butter is a food, a mixture of compounds - not a change.
