Each Phase of matter can be described according to the relative amount of attractive intermolecular forces (IF) holding the molecules together compared to the kinetic energy (KE) of those molecules. Drag each of the following phases of matter to the proper description of its intermolecular forces and kinetic energy of molecules.
