Which of the following is an example of chemical change?

Correct option is A

The softening of vegetables when cooked is an example of a chemical change. When vegetables are cooked, the heat causes a breakdown of cell walls and changes in the chemical structure of the substances within the vegetables, resulting in a softer texture.
Important Key Points:
1. Cooking vegetables leads to a chemical change as heat alters their chemical structure.
2. The softening is due to the breakdown of pectin and cellulose in the cell walls.
3. Chemical changes are often irreversible, unlike physical changes.
4. Other examples of chemical changes include rusting of iron, burning of wood, and baking of bread.
