The energy must be supplied to the solid so that it melts.
When energy is supplied to a solid, the particles within the solid gain energy and vibrate more rapidly. This increase in thermal energy causes the particles to move further apart, leading to expansion of the solid.
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.
As energy is taken away from a substance, the particles within the substance slow down and lose kinetic energy. Eventually, the particles may form a solid structure as they come closer together due to the reduction of thermal energy.
As thermal energy decreases, the particles in a substance slow down and have less kinetic energy. This may cause them to move closer together, leading to a decrease in the substance's volume or a change in state, such as from a gas to a liquid or a solid.
The internal energy of a solid substance is primarily made up of kinetic energy of its atoms and molecules due to their motion and vibrations within the solid structure.

when solid has already melted and when heat is supplied it starts increasing the temperature of liquid

What happens to a solid when energy is removed
Its molecules starts vibrating more than when they were solid. Their kinetic energy are greater.

The solid changes into a liquid
When thermal energy is removed from a substance, the molecules lose kinetic energy and slow down. This often causes the substance to cool down as the molecules have less energy to move and vibrate. In extreme cases, the substance may undergo a phase change, such as from a liquid to a solid.
