What are the prerequisites for condensation answer in one sentence
Firstly, the presence of water vapour in the atmosphere is required for condensation to occur.
Secondly, low temperature is important as it decreases the moisture holding capacity of the air which leads to condensation..
What are examples 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 fog an example of condensation
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets.
Is heat absorbed or released in condensation
The condensation is the opposite process of evaporation. The heat of condensation is numerically exactly equal to the heat vaporization, but has the opposite sign. … In the case of evaporation, the energy is absorbed by the substance, whereas in condensation heat is released by the substance.
What happens to heat during condensation
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 3 conditions are needed for condensation to form
The process requires the presence of water vapor in the atmosphere, falling temperature and the presence of another object for water vapor to condense around.
What are three examples of condensation
Ten Common Condensation ExamplesMorning Dew on the Grass. … Clouds in the Sky. … Rain Falling Down. … Fog in the Air. … Visible Breath in Cold Conditions. … Fogging a Mirror. … Steamy Bathroom Mirror. … Moisture Beads on Car Windows.More items…
What must happen for condensation to occur quizlet
Air must cool to the dew point temperature. What must happen for condensation to occur? … The air becomes supersaturated.

What happens before condensation
Condensation is the change of water from its gaseous form (water vapor) into liquid water. 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.
How do you determine if condensation will occur
Air temperature, combined with humidity level, defines a temperature at which condensation will form. This is called the Dew Point Temperature. If condensation is forming, then the humidity percentage must be reduced so the resulting Dew Point Temperature is below the temperature of the cooler surfaces.
How does heat affect condensation
Heating water increases the rate of evaporation. … The water vapor molecules lose kinetic energy and condense on the cooler surfaces inside the cup. The drops are largest on the plastic wrap closest to the ice. As air cools, the rate of condensation of water vapor in the air increases.
When air is forced to rise what happens
Air moves into a Low pressure system. It pushes any air that was there upwards.
What are 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.
How does condensation happen
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. Dew point is the temperature at which condensation happens. … When a pocket of air becomes full of water vapor, clouds form.
Does condensation need heat
Latent heat is the heat energy required to change a substance from one state to another. … Energy is required to change from solid to liquid, liquid to gas (evaporation), or solid to gas (sublimation). Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid.
Which event is an example of condensation
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. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
Where does condensation occur quizlet
the conversion of water from a gas into a liquid” It said how condensation occurs. It said, ” Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. ” So that is how condensation occurs. It occurs by the atmosphere.
