Does Chlorine Evaporate?

Liquid chlorine evaporates very quickly. One pound of liquid chlorine forms 5.4 cubic feet of chlorine gas when evaporated. Liquid chlorine is chlorine that has been cooled and compressed.

Chlorine will evaporate if it is poured into water, soil or is released from a chlorine tank. When chlorine evaporates it forms a greenish-yellow cloud that can be carried away by the wind. Chlorine that is in the air is broken down by sunlight in minutes. Chlorine that is added to water is dissolved and is converted into chloride and hypochlorous acid. The hypochlorous acid that is created from the dissolved chlorine is used to treat swimming pool water.
