What does the melting process signify in terms of changes of state?

• A. Liquid to gas
• B. Solid to liquid
• C. Gas to solid
• D. Liquid to solid

Answer: (B)

The melting process signifies a change from solid to liquid. This transformation occurs when a solid reaches a certain temperature, known as the melting point, where the thermal energy provided to the solid overcomes the forces holding its particles in their fixed positions. As a result, the particles begin to move more freely, resulting in the solid changing into a liquid state. This is a fundamental concept in understanding phase changes in matter and is essential in fields related to chemistry and materials science, as it demonstrates how temperature influences the state of substances.
