What is an example of a chemical change?

Cutting an avocado
Boiling water
Dissolving sugar
Bending a spoon

The correct answer is: Dissolving sugar

An example of a chemical change is dissolving sugar. In this process, the molecules of sugar break apart and rearrange into different molecules known as sucrose, glucose, and fructose. These new molecules have different properties and composition than the original sugar molecules, making this a chemical change. The other options, cutting an avocado, boiling water, and bending a spoon, are all examples of physical changes. These changes do not alter the chemical identity of the substances involved, but rather their physical properties such as shape, state, or form. Cutting an avocado changes its shape, boiling water changes its state from liquid to gas, and bending a spoon changes its form. Only dissolving sugar involves a chemical reaction, making it the correct answer for an example of a chemical change.
