Understand the Problem
The question is asking to identify which option represents a change of state. Changes of state refer to the transitions between solid, liquid, and gas phases of matter, such as melting or freezing. We will analyze each option to determine if it describes such a transition.

More Information
A change of state is when a substance transitions from one state of matter (solid, liquid, gas) to another. Chocolate melting is a transition from solid to liquid, which is a change of state.
Tips
A common mistake is to confuse chemical changes (like wax becoming carbon dioxide and water) with physical changes (changes of state).
