matter phasesphase to phase transition 5Condensation is a physical change of a substance from a gas phase to a liquid phase.  The molecules are fast moving and far apare.  So as the temperature starts to cool or the pressure increases which lowers the volumn, the molecules slow down and come closer togeather.  As the gas reaches a certain energy level the vapor changes to liquid.  Certain natural events cause condensation of water vapor in the atmosphere such as clouds, fog, and mist.

There are four phases of matter: gas, liquid, plasma, and solid.
