dennislmay Posted October 1, 2012 Share Posted October 1, 2012 When the water is cooler, it evaporates. When the water is hotter, it does not evaporate. Why?1:19 In the hotter pan the water droplets are floating on an insulating layer of steam - acting like a hovercraftwith surface tension holding the water into large extended drops.This only works as long the steam has a way out [smaller extended drops]. If you continue to add waterthe steam then boils and most of the water is back in contact with the pan instead of floating over it.Dennis Link to comment Share on other sites More sharing options...
