SUBLIMATION - the transition of a substance directly from the solid to the gas state, without passing through the liquid state.

VAPORIZATION - conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling.

INTERMOLECULAR FORCE - forces are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles

CONDENSATION - the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water

DIFFUSION - the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.
