A blue color is typically a physical property since it relates to the appearance of a substance and can be easily observed without undergoing a chemical change. Chemical properties, on the other hand, describe how a substance interacts with other substances in terms of its chemical composition and reactivity.
The blue-gray color of silicon is a physical property. Physical properties are characteristics that can be observed or measured without changing the composition of the substance, like color, density, and melting point.
The blue color of copper II sulfate pentahydrate is a physical property, as it refers to an observable characteristic of the substance without changing its chemical composition. Chemical properties, on the other hand, describe how a substance reacts with other substances to form new products.
The color of the sky being blue is a physical property, not a physical or chemical change. It is due to the scattering of sunlight by the Earth's atmosphere, particularly by air molecules and small particles in the atmosphere.
Can't say why or why not, because it sin't a reaction at all! Blue is a color, thus a physical substance(s) property
