    distillation‚ first consider what happens upon heating a liquid. At any temperature‚ some molecules of a liquid possess enough kinetic energy to escape into the vapor phase (evaporation) and some of the molecules in the vapor phase return to the liquid (condensation). An equilibrium is set up‚ with molecules going back and forth between liquid and vapor. At higher temperatures‚ more molecules possess enough kinetic energy to escape‚ which results in a greater number of molecules being present in the vapor

    storms‚ which are warm water and moist‚ warm air. Hurricanes occur when the moist‚ warm air from the surface of the ocean rises and meets the cooler air. When the moist‚ warm air condenses and forms storm clouds and raindrops. Heat releases and the condensation process begin. It goes through a cycle that causes the humid air from the ocean surface to rise and join the storm that is forming. The cycle of exchanging heat continues and wind pattern is created that moves in a spiral fashion around the center
