Is a green tomato turning red chemical change?

* Chemical Composition: Green tomatoes contain chlorophyll, which gives them their green color. As the tomato ripens, the chlorophyll breaks down and is replaced by lycopene, a red pigment.

* New Substances Formed: The breakdown of chlorophyll and the formation of lycopene are chemical reactions. This means new substances are being created with different properties than the original substances.

* Irreversible Change: The red color change is permanent. You can't turn a ripe red tomato back into a green one without significant intervention.

In summary: The process of a green tomato turning red involves chemical reactions that result in the formation of new substances and a permanent color change.
