Chapter 3, Problem 44A

Interpretation Introduction

Interpretation:

Whether the process of bananas ripening is a chemical change or a physical change needs to be determined.

Concept introduction:

The nature of any substance is explained by their chemical properties and physical properties.

A physical property describes the physical changes of a substance. Physical change is a temporary change; it is a reversible change. For example, color, mass, volume, etc.

A chemical property describes how a substance reacts with other substances. In a chemical change, a new substance is formed and absorption of energy or loss of energy occurs; it is an irreversible change. For example, rusting, dissolving, etc.

Answer to Problem 44A

Ripening fruit is a chemical change.

Explanation of Solution

Conversion of the state is a physical change, where the only position of molecules changes but their composition remains similar in both states.

The ripening of fruit is a biochemical change. In this process, some chemical changes occur in the composition of the fruit. Here, formation of a new product will take a place. The ripening of fruit is an irreversible process. So, it is considered a chemical change.

Conclusion

The ripening of fruit is an irreversible process. So, it considers as a chemical change.
