| Research Abstract |
We demonstrate phase transition of water from vapor to liquid at undersaturation by photochemically-induced droplet formation. Water droplet was formed upon irradiating unsersaturated ambient air by UV lamp (Hg lamp, 185 nm). This experiment demonstrates that thermodynamic reverse change occurs by photochemical reaction. Hydrogenperoxide was detected in droplet. We discussed practical application in field.
