When a solid is changed to a liquid phase, it absorbs energy from the surroundings in the form of heat. This is because the particles in the solid are closely packed and have low kinetic energy, whereas in the liquid phase, the particles have more kinetic energy and are farther apart. This energy input breaks the intermolecular forces holding the solid together and allows the particles to move into new positions as a liquid.
