When heat energy equal to the latent heat of fusion is supplied to a solid at its melting point, the energy is used to break the intermolecular bonds holding the particles in the solid state rather than increasing their kinetic energy. As a result, the temperature remains constant during the phase change, and the solid transitions into a liquid. The kinetic energy of the particles increases only after the phase change is complete and additional heat is supplied, leading to an increase in temperature.
The kinetic energy exceeds the inermolecular forces (Apex)
The kinetic energy increase.
During melting and boiling, the temperature remains constant because the heat energy supplied is used to break intermolecular bonds rather than increase kinetic energy. In melting, energy disrupts the structured arrangement of solid particles, while in boiling, it allows liquid particles to escape into the gas phase. This phase change requires energy, but does not result in a temperature increase until the phase transition is complete.
you must have observed during the experiment of melting that the temperature of the system does not change after the melting point is reached till all the ice melts this happens even though we continue to heat the breaker that is we continue to supply heat
During melting the temperature remain constant if it was achieved the melting point.
when solid has already melted and when heat is supplied it starts increasing the temperature of liquid
When heat is supplied to a solid, the kinetic energy of the particles increases, they move away from each other
The kinetic energy exceeds the inermolecular forces (Apex)
The kinetic energy increase.
As a substance is heated to its melting point, the kinetic energy of its particles increases, causing them to move more rapidly. This increase in kinetic energy leads to a rise in temperature until the substance reaches its melting point. At the melting point, the kinetic energy is used to overcome the forces holding the particles together, leading to the substance changing from a solid to a liquid state.
A melting ice cube's kinetic energy comes from the movement of the water molecules as they transition from a solid to a liquid state. This energy is relatively low due to the slow and gradual process of melting.
When particles reach their melting point, they absorb enough energy to transition from a solid to a liquid state while maintaining their molecular structure. During melting, the particles gain kinetic energy, causing them to vibrate more rapidly and move further apart, which leads to the solid substance turning into a liquid.

Well...kinetic energy is involved with melting
During the phase change of a solid to a liquid (melting), all of the energy goes into breaking the intermolecular bonds holding the molecules of the solid together, and none of the energy goes into changing the temperature. Thus, during this particular phase of melting, the temperature of the system does NOT change.
During melting the temperature remain constant if it was achieved the melting point.
This is because of latent heat. When a substance is being melted, heat is supplied to the solid until its melting point is reached. When the solid reaches that temperature, any additional heat energy is used - not to raise its temperature - but to cause the phase to change from solid to liquid. The amount of energy required (per unit mass) is the latent heat of melting (or freezing, when the process is reversed) for that substance. When the phase change is complete, any further heat energy supplied will, once again, go towards raising the temperature.The same thing happens at the boiling point except that this time it is the latent heat of evaporation/condensation.
