www.nios.ac.inmolecules which are held together by intermolecular forces. At room temperature, these atoms/molecules have finite thermal energy. If thermal energy increases, molecules begin to move more freely. This state of matter is said to be the gaseous state. In this state, intermolecular forces are very weak and very small compared to their kinetic energy.

AP Chemistry Scoring Guidelines, 2016
secure-media.collegeboard.orgonly possible intermolecular forces are London dispersion forces. The London dispersion forces are stronger in I because it is larger in size with more electrons and/or a more polarizable electron cloud. The stronger London dispersion forces in I result in a higher melting point,which makes I 2 a solid at room temperature.

Food-coloring molecules are usually ionic solids, that is, they contain positive and negative ions, which are held together by ionic bonds.
