Melting is an endothermic process.
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.

When matter melts, the energy is used to break the bonds holding the solid structure together, causing the particles to move more freely. This increase in energy leads to a change in state from solid to liquid, without any increase in temperature. The energy required for melting is known as the heat of fusion.
No. They gain.
It melts. Energy is absorbed.
When a solid melts, thermal energy is absorbed to break the bonds between the particles. This increase in thermal energy causes the particles in the solid to gain enough kinetic energy to overcome the attractive forces holding them together, resulting in the solid turning into a liquid.

Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.

When ice melts it is called a physical endothermic change.
