The formation of a yellow color when two clear liquids are mixed is indicative of a chemical change for several reasons:
1. **New Substance Formation**: In a chemical change, reactants combine to form new substances with different properties. The appearance of a yellow color suggests that a new substance has been formed that has different optical properties compared to the original clear liquids.
2. **Color Change**: Color changes are often associated with chemical reactions. When two clear liquids mix and produce a distinct color, it usually means that a reaction has taken place, resulting in the formation of a new compound or compounds.
3. **Irreversibility**: Chemical changes are typically not easily reversible. Once the yellow color forms, it may be difficult or impossible to revert the mixture back to its original clear liquids without additional chemical processes.
4. **Energy Change**: Many chemical reactions involve energy changes (exothermic or endothermic) during the formation of new substances. While this may not be directly observable in every case, the change in color could be accompanied by other energy-related changes.
In summary, the emergence of a yellow color upon mixing two clear liquids is a strong indicator of a chemical change, suggesting that a chemical reaction has occurred, resulting in new substances with different properties.
