**Heat Transfer during Melting**
When a solid melts, its temperature remains constant during the phase change. This phenomenon occurs due to the absorption of heat energy by the solid during the process of melting. The heat energy supplied to the solid is utilized to break the intermolecular forces or bonds between the particles of the solid, rather than increasing the temperature of the substance.
**Explanation:**
During the process of melting, the heat energy is used to overcome the intermolecular forces or bonds holding the solid particles together. These forces, which are typically weaker compared to the covalent or ionic bonds within the molecules or atoms, need to be broken in order to convert the solid into a liquid state.
**The heat energy goes through the following steps during the melting process:**
1. **Temperature remains constant**: When heat energy is supplied to a solid, the temperature does not increase because the energy is being utilized to overcome the intermolecular forces rather than increasing the kinetic energy of the particles.
2. **Breaking intermolecular forces**: The heat energy absorbed by the solid is used to weaken or break the forces of attraction between the particles. These intermolecular forces include hydrogen bonding, dipole-dipole interactions, or London dispersion forces, depending on the type of solid.
3. **Potential energy increases**: As the intermolecular forces are overcome, the particles gain potential energy. This potential energy allows the particles to move more freely and enables them to transition from a solid to a liquid state.
4. **Phase transition**: Once enough heat energy is supplied to the solid, the particles gain sufficient potential energy to overcome the intermolecular forces completely. At this point, the solid undergoes a phase transition and transforms into a liquid.
It is important to note that the heat energy absorbed during melting is known as latent heat or heat of fusion. This energy is used to change the state of the substance rather than increasing its temperature. Once the solid has completely melted, further addition of heat energy will increase the temperature of the liquid.
