When an animal or species adopts to their suroundings. example, a species of white moths live in a community, very bountiful. Then some trees of a nearby forest get cut down leaving some birds homeless. so they go to the town with all the moths, the moths stick out so the are rapidly eaten. so they slowly change color, then they get darker and they become harder to see.
color is a physical and intensive property
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
it is a chemical change
yes and no
yes they do!
Eye color is a physical change, not a chemical change. Eye color is determined by the amount and distribution of melanin in the iris, which is a physical characteristic that can change over time but does not involve any chemical reactions.
A physical change, of course. A physical change includes change in shape, color, or texture.
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
no, a physical change
Change in Color.
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.
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
