Condensation

In clouds, this can be catalyzed by water-nucleating proteins, produced by atmospheric microbes, which are capable of binding gaseous or liquid water molecules.

Condensation commonly occurs when a vapor is cooled and/or compressed to its saturation limit when the molecular density in the gas phase reaches its maximal threshold.

Commercial applications of condensation, by consumers as well as industry, include power generation, water desalination,[4] thermal management,[5] refrigeration,[6] and air conditioning.

Condensation in building construction is an unwanted phenomenon as it may cause dampness, mold health issues, wood rot, corrosion, weakening of mortar and masonry walls, and energy penalties due to increased heat transfer.

This can be done in a number of ways, for example opening windows, turning on extractor fans, using dehumidifiers, drying clothes outside and covering pots and pans whilst cooking.

[8] However, this can be a double edged sword as most condensation in the home occurs when warm, moisture heavy air comes into contact with a cool surface.

In cloud chambers a liquid (sometimes water, but usually isopropanol ) condenses upon contact with a particle of radiation thus producing an effect similar to contrails
