- Title
Condensation of Water Vapour in Ambient Atmosphere Under Applied Pressure at Room Temperature A Demonstration Experiment.

- Abstract
The article demonstrates the condensation of water vapour under pressure and at room temperature, using a disposable syringe and an ambient light source. The small amount of trapped water vapour inside a syringe along with the air is compressed manually to one-sixth of its original volume. The compressed water vapour inside the syringe can be easily seen in the form of a white condensate on the inner side of the transparent, circular wall of the syringe. The condensate cloud can be observed in the atmosphere by releasing it in the open air while holding the syringe in front of a light source over a dark background. This model can be used as an analogous experiment while explaining the concept of condensation of gases under pressure-from school to postgraduate students.
