Final answer:
A change from solid to liquid is a physical change, characterized by alternation in state while maintaining unchanged chemical composition. This process is represented by melting and is reversible, like many other physical changes.
Step-by-step explanation:
The statement that describes a physical change is 'A change in state from solid to liquid'. A physical change involves a transition in one or more physical properties of matter without altering its chemical composition.
For instance, when ice, a solid, melts to water, a liquid, this is an example of melting, which is a physical change. It is important to note that during such a transformation, while the physical state changes, the molecular structure of water (H₂O) remains unchanged. This contrasts with a chemical change, where there is a change in chemical composition involving a chemical reaction.
Additional examples of physical changes include the freezing, boiling, or dissolving of substances. These are usually reversible processes, such as water vapor condensing back into liquid, demonstrating the reversible nature of many physical changes.
