Answer:
The behaviour of molecules in different phases of matter represents a balance between the kinetic energies of the molecules and the attractive forces between them. All molecules are attracted to each other. ... The molecules are in the solid state. At higher temperatures, the kinetic energy of the molecules is higher.
