Change of State: Condensation, Sublimation, and Deposition
Have you ever noticed droplets forming outside a cold glass on a warm day? This phenomenon is called condensation. It is the process where a gas changes into liquid form due to cooling.
When warm and moist air touches the cool surface of the glass, it loses energy. As the air cools down, its invisible water vapor turns into tiny water droplets.
This process plays a key role in forming dew, fog, clouds, and Earth's water cycle.
Another fascinating change of state is sublimation, in which a solid substance changes directly into a gas, skipping the liquid phase.
For example, mothballs shrink over time as the solid sublimates into gas without melting.
In contrast, deposition is the process in which a gas transforms directly into a solid without changing to liquid.
For instance, delicate ice crystals sparkle on a windowpane on a cold morning. They form when water vapor in the air skips the liquid stage and freezes directly into ice.
These processes—condensation, sublimation, and deposition—illustrate the transformation of matter and its role in Earth's water cycle.
