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 happens to the molecules when condensation occurs?
Condensation happens when molecules in a gas cool down . As the molecules lose heat, they lose energy and slow down. They move closer to other gas molecules. Finally these molecules collect together to form a liquid.
What happens during condensation?
Condensation is the process by which water vapor in the air is changed into 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.
What will happen after condensation?
After Water Condenses
Latent heat from condensation causes an increase in air temperature surrounding the water droplets . ... Liquid or frozen water falls to the surface as precipitation. It can be stored as solid particles in snow or ice or as a liquid in bodies of water.
What causes the condensation to occur?
Condensation occurs when warm air collides with cold surfaces , or when there's too much humidity in your home. When this moisture-packed warm air comes into contact with a chilly surface, it cools down quickly and releases the water, which turns into liquid droplets on the cold surface.
What are the 4 types of condensation?
After condensation the water vapour or the moisture in the atmosphere takes one of the following forms — dew, frost, fog and clouds .
What is a good example of condensation?
Clouds are a large-scale example of condensation, and generally form when water vapor in warm air rises to meet cold air higher in the atmosphere. As the warm air cools and the molecules coalesce and stick together, drops of water or ice crystals form and surround dust particles in the air.
How do you show condensation?
Fill a cup approximately two-thirds full of hot water. Take another cup, flip it upside down, and place it on top of the cup with hot water. Then place an ice cube on top of the upside down cup . Condensation will begin to form at the top of the upside down cup, just like a cloud.
Which event is an example of condensation?
Common examples of condensation are: dew forming on grass in the early morning , eye glasses fogging up when you enter a warm building on a cold winter day, or water drops forming on a glass holding a cold drink on a hot summer day. Condensation occurs when water droplets form due to cooling air.
Is heat released during condensation?
A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Heat is released when a vapour condenses .
Where does condensation happen?
Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor . As a result, excess water vapor condenses to form cloud droplets.
What happens right before evaporation occurs?
Evaporation happens when a liquid turns into a gas . ... When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice. When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it evaporates and becomes a gas—water vapor.
What three things are needed for condensation to occur?
Visible and Concealed Condensation
Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point . The proper control of these two factors can minimize condensation.
How can I prevent condensation?
- Try to keep the inside temperature reasonably constant.
- Avoid drying clothes indoors.
- Do not dry clothes over any radiators.
- Ensure tumble driers are properly vented or the condensate is regularly emptied.
- Keep furniture away from walls.
- Do not turn off or disable extractor fans.
What evidence do you have that condensation is taking place inside your house?
If the air gets colder it cannot hold all the moisture and tiny drops of water appear . This is condensation. You also notice it when you see your breath on a cold day, or when the mirror mists over when you have a bath. Kitchens and bathrooms are often primary sources of atmospheric water.
