Condensation occurs when excess moisture in the air settles on cool surfaces.
Air's capacity to hold moisture varies with temperature; colder air holds less moisture. When air cools and reaches its dew point (the temperature at which it becomes saturated), the water vapor in the air condenses into liquid water on nearby surfaces. This is why you see condensation on cold objects like windows or mirrors in a humid environment.
Here's a breakdown:
- Moisture Capacity: Warm air can hold more moisture than cold air.
- Dew Point: The temperature at which air becomes saturated with water vapor.
- Cool Surfaces: Condensation is more likely to occur on surfaces that are cooler than the surrounding air.
For example, think of a cold glass of iced tea on a warm day. The air around the glass cools down, and the moisture in the air condenses on the cold surface of the glass. Another common example is condensation on bathroom mirrors after a hot shower, as the hot water introduces excess moisture into the air.
Condensation is a natural process and can be managed through ventilation, dehumidification, and insulation.
