Understanding the Melting Process
During the melting process, a substance transitions from a solid to a liquid state. This phase change is crucial in understanding thermal dynamics.
Temperature Behavior During Melting
- When a solid begins to melt, it absorbs heat energy from its surroundings.
- The temperature of the substance remains constant throughout the melting process, despite the input of heat. This is because the energy is utilized to break the intermolecular bonds holding the solid structure together, rather than increasing the kinetic energy of the particles.
Key Points to Remember
- **Constant Temperature**: The temperature does not increase or decrease; it stays at a specific melting point until all the solid has transformed into liquid.
- **Absorption of Heat**: The heat energy absorbed during the melting phase is referred to as the latent heat of fusion.
- **Phase Change**: This phase change is characterized by the transition from ordered (solid) to disordered (liquid) molecular arrangements.
Conclusion
In conclusion, during the melting process, the temperature of a substance remains constant (option 'C') until the entire solid has melted. Understanding this concept is vital for grasping broader principles in thermodynamics and material science, particularly in fields such as physics and chemistry.

During the melting process, the temperature of the substance remains constant even though heat is continuously supplied. This is because the heat energy is used to overcome the forces holding the particles together rather than increasing the temperature. This constant temperature is known as the melting point.
