On a microscopic level, the particles in the gallium will begin to move more rapidly as it melts. The solid arrangement of particles will start to break down as they gain more kinetic energy. Ultimately, the particles will rearrange themselves into a liquid state, with the individual particles moving more freely and having more space between them compared to when the gallium was in its solid state.
