I’m asking you
Physical Property
yes
No, it is a chemical change Iron turns green means it is oxidized to ferrous (Fe+2) state.
Luster is a physical property.
Red color is a physical property because it can be observed without changing the chemical makeup of the substance. It is a result of the way light interacts with the material and is a characteristic that can vary based on factors like pigmentation or structure.
The color red results as a reflection from a particular wavelength of light off a compound in the skin of the apple. The compound in the skin is a chemical compound. The light ray is physical.
Yes, the color of elemental bromine being orange-red is a chemical property. Chemical properties describe how a substance reacts with other substances or changes chemically to form new substances, and in the case of elemental bromine, its distinct orange-red color is a characteristic that is specific to its chemical composition.
Hemoglobin molecules having a red color is not considered a chemical property, but a physical property. Chemical properties involve the way a substance interacts with other substances in chemical reactions, while physical properties relate to observable characteristics like color, density, and melting point.
The color change of elemental bromine from red to orange is a physical change. This is because the substance's chemical composition remains the same; only its physical appearance, in this case its color, is altered.
Its colour, its melting point, its boiling point, whether it is magnetic or not, whether it is an electrical conductor or not and its atomic mass are all physical properties.
Physical Reaction
One physical property of an acid is that it has a sour taste.
