When does the color change in a leaf indicate physical change and when dos it indicate chemical change?
The color change in a leaf typically indicates a chemical change when it results from the breakdown of chlorophyll and the revealing of other pigments, such as carotenoids and anthocyanins, as the plant prepares for winter. This process involves biochemical reactions that alter the pigments present in the leaf. Conversely, a physical change may be indicated if the color change is due to external factors like exposure to light or temperature without altering the leaf's chemical composition.

What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
Is changing color of a carnation a chemical or physical change?
It is a chemical change.
17 Explain how color can be classified as both a physical property and as one indication of a chemical change?
Color can be classified as a physical property because it can be observed without changing the chemical composition of a substance. However, color change can also indicate a chemical change when it is a result of a reaction that alters the molecular structure of the substance, leading to a new chemical identity. In this case, the color change is a visual representation of the chemical transformation that has occurred.
When you dye your hair is that physical change or chemical change?
Yes it is a chemical change because color change is an observed change that a chemical change has occurred. So you are very much right. :)
Is food color is dropped into water to give it color a chemical change?
no, a physical change
What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
If the color changes it is a chemical or physical?
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
What does not signal a chemical change color change or production of light and heat or production of gas or change in state?
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.
Is the Change of color a physical change?
it is a chemical change
Is the eye color physical or chemical change?
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.
