The ripening of a banana in which the skin turns yellow and it tastes sweet is an example of what change???
physical or chemical?????
Chemical.
To determine whether the ripening of a banana is a physical or chemical change, we need to understand the difference between the two.
A physical change refers to a change in the physical properties of a substance, such as its shape, size, or state of matter, without any alteration in its chemical composition. Examples of physical changes include melting, boiling, crushing, or dissolving.
On the other hand, a chemical change refers to a process in which a substance undergoes a chemical reaction, resulting in the formation of new substances with different chemical compositions. These changes often involve the breaking and forming of chemical bonds. Examples of chemical changes include burning, rusting, fermentation, and digestion.
In the case of a banana ripening, it involves a complex series of chemical reactions occurring inside the fruit. As the banana ripens, enzymes within the fruit break down complex carbohydrates into simple sugars (such as glucose, fructose, and sucrose), which results in the fruit's sweet taste. This chemical reaction is accompanied by the release of ethylene gas, which accelerates the ripening process. The skin of the banana also changes color, turning from green to yellow, which is due to the breakdown of chlorophyll pigments.
Since the ripening of a banana involves chemical reactions, it is considered a chemical change rather than a physical change.
