Can condensation be reversible?
Yes it can. Prove this to yourself by filling glass with ice and water. Water from the air condenses on the outside. Empty the glass and put it back down without wiping the outside (drops still in place) As the glass returns to room temperature the condensed water evaporates back into the air. Evaporation is the opposite of condensation.
