As aluminum gets hot, the solid metal expands before melting. what best explains this phenomenon? a. the atoms collide with greater force, fusing their nuclei together. b. the atoms eject electrons, becoming positive ions that repel each other. c. the atoms chemically react with each other, releasing heat that melts the solid metal. d. the atoms move faster, increasing the distance between them before breaking some of their bonds.
