Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
What is the process that occurs when water changes from liquid to gas?
Evaporation is the process by which water changes from a liquid to a gas or vapor.
Which is an example of the process of condensation?
The air is full of water, as water vapor, even if you can’t see it. Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head.
When does condensation of a liquid release heat?
Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing. When steam, which is gaseous water, condenses, heat is released. Likewise when liquid water freezes, heat is given off. And this stored energy is let out as exothermic heat.
How are water molecules arranged in the vapor form?
Water molecules in the vapor form are arranged more randomly than in liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result. The little cloud that could—but why?
How does condensation lead to the formation of fog?
Fog develops when air having a relatively high humidity comes in contact with a colder surface, often the Earth’s surface, and cools to the dew point. Additional cooling leads to condensation and the growth of low-level clouds. Fog that develops when warmer air moves over a colder surface is known as advective fog.
