They gain energy, move more rapidly, and slide around each other becoming fluid.
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.
When a solid is heated without melting, its particles vibrate more rapidly due to increased thermal energy. This causes the solid to expand slightly and its temperature to rise. If the heating continues, the solid will eventually reach its melting point and transition into a liquid state.

Increasing the temperature up to the melting point.
When a solid is heated and its temperature rises, the kinetic energy of the particles in the solid increases. This causes the particles to vibrate more vigorously and further apart, leading to expansion of the solid. Eventually, the solid may reach its melting point and transition into a liquid state.
melting
The freezing point and melting point of a substance are the same temperature, known as the equilibrium melting point, at which the solid and liquid phases coexist in equilibrium. When a substance is cooling down, it will reach its freezing point temperature, causing it to solidify. Conversely, when a substance is heating up, it will reach its melting point temperature, causing it to liquefy.
Each substance has a specific melting point (excepting cases of sublimation or thermal degradation).
When solids reach their melting points, they become liquids. This is the point at which the intermolecular forces holding the solid together are overcome, allowing the particles to move more freely and flow as a liquid.
When heat is added to a solid, its particles start vibrating more rapidly, increasing their kinetic energy. This causes the solid to expand slightly as the particles spread out. If enough heat is added, the solid may reach its melting point and turn into a liquid.
you must reach its melting point or freezing point or boiling point.
When a metal rod is heated, its particles gain kinetic energy and begin to vibrate more rapidly. This increased motion causes the rod to expand due to thermal expansion. As the rod continues to heat up, it may eventually reach its melting point, at which point it will melt and turn into a liquid.
