Which of the following refers to the state change from solid to liquid?

1. Condensation.

2. Melting.

3. Sublimation.

4. Freezing.

The correct answer is: Melting.

The process of changing from a solid to a liquid is known as melting. This phase transition occurs when the temperature of a solid rises to its melting point, allowing the molecular structure to break down and enter a liquid state. In contrast, condensation refers to the transition from gas to liquid, while sublimation is the process of a solid converting directly to a gas without becoming a liquid first. Freezing is the opposite of melting, as it describes the transition from liquid to solid. Understanding these distinct phase changes is crucial in many scientific fields, including chemistry and physics, as they describe fundamental behaviors of matter under various conditions.
