Melting is the process that changes a solid to which state?

• A. Solid to Gas
• B. Gas to Liquid
• C. Solid to Liquid
• D. Liquid to Gas

Answer: (C)

Melting is the change from a solid to a liquid when heat is added. In a solid the particles are held in a rigid structure by strong forces. As the temperature rises, they gain kinetic energy and vibrate more until, at the melting point, enough energy is absorbed to break the bonds holding the solid together, allowing the particles to move past one another and flow as a liquid. So the state after melting is a liquid. The other possibilities describe different phase changes: solid to gas is sublimation, gas to liquid is condensation, and liquid to gas is vaporization.
