Condensation is the process where water vapour becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapour. Condensation happens one of two ways: The air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
In everyday life, you often see condensation on surfaces like windows, mirrors, or cold drinks. This process is a normal part of the water cycle and can occur naturally or due to environmental conditions.
Condensation from windows is a common issue that occurs when moist air comes into contact with a cooler window surface, causing the water vapour in the air to condense into liquid droplets. There are different types of condensation, depending on where it forms on the window, and each has specific causes, effects, and solutions.
