Why does water vapor condense up in the atmosphere?
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. (Dew is simply condensed water in the atmosphere.)
What happens to water vapor as it moves higher in the atmosphere?
As water vapor rises higher in the atmosphere, it begins to cool back down. When it is cool enough, the water vapor condenses and returns to liquid water. These water droplets eventually gather to form clouds and precipitation.
What causes water vapor to move from over water to over land?
Pagination. The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.
When water vapour condenses near the ground there is?
Fog is formed of condensed water droplets when the water vapor in the air near the ground cool. Fog can form after rain cools and dampens low-lying air.
Why does water vapor in the air condense when the air is chilled?
Why does water vapor in the air condense when the air is chilled? Cool air contains more slow water molecules, which stick together more often when they collide.
Why does water vapor decrease with altitude?
Altitude and height play an important role in vaporization of the water as water vapours are heavy and at higher altitude, the air density decreases. Thus, it becomes difficult for heavier particles that make water vapours to get vaporized. Hence, the rate of water vaporization decreases with increase in altitude.

How does evaporated water migrate from being over the ocean to being over the land?
Condensation is a major step in the water cycle. The atmosphere helps to move water around the world. It takes water that evaporated from the ocean and moves it over land where clouds and storms form to water plants with rain. Precipitation is when water falls from the atmosphere back to land.
Why does water vapour decreases from equator to pole?
Water vapor decreases from equator to pole due to temperature (lower temperatures mean lower absolute humidity), and increases over ocean compared with land (because of the availability of water to evaporate).
Where do water particles condense in atmosphere?
The air is full of water, even if you can't see it. Higher in the sky where it is colder than at the land surface, invisible water vapor condenses into tiny liquid water droplets—clouds.
Why does condensation form most rapidly on the coldest object in a room for example on a glass of ice water?
Warm air can absorb more moisture from the cold object than the warm object. This is the reason why condensation occurs rapidly on the coldest object.
Why does water vapour decreases from equator to poles?
Water vapor decreases from equator to pole due to temperature (lower temperatures mean lower absolute humidity), and increases over ocean compared with land (because of the availability of water to evaporate).
Does water vapor increase with altitude?
The amount of water vapor is the air tends to decrease with altitude. This is because temperatures decrease with height and the availability of a moisture source is farther away.
What is condensation short answer?
Condensation is the process by which water vapor in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapor, from your hot shower cooled when it met the surface of the cold mirror. This caused the water vapor to condense, or turn into its liquid form.
What are some fun facts about condensation?
Fog and dew are formed by condensation that occurs closer to the Earth's surface. The temperature at which condensation occurs is called the dew point. Dew is made of microscopic water particles that form when water vapor collides with the low temperature of the atmosphere and condenses back into water.
Why does the water evaporate and get lost to the atmosphere?
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.
Why does water vapour decrease with altitude?
Altitude and height play an important role in vaporization of the water as water vapours are heavy and at higher altitude, the air density decreases. Thus, it becomes difficult for heavier particles that make water vapours to get vaporized. Hence, the rate of water vaporization decreases with increase in altitude.
What happens to water vapor as altitude increases Why?
Because air is cooler at higher altitude in the troposphere, water vapor cools as it rises high in the atmosphere and transforms into water droplets by a process called condensation.
What is condensed water vapor?
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.
Why does condensation occur?
The humidity of indoor air – As we touched on before, condensation forms when the inside air can't hold the level of moisture. Low temperature – The humid air comes into contact with cold indoor surfaces.
What causes condensation on a glass of ice water?
What happens is that the air immediately surrounding the glass of ice water is cooled close to freezing. Moisture in the air will condense out once the temperature of the air drops below the initial dewpoint of the air.
Why does the amount of water vapour in the air decreases with increase in height above mean sea level?
Earth's gravity pulls air as close to the surface as possible. The second reason is density. As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.
How do you explain condense to a child?
Condensation is the process by which water vapor (water in its gas form) turns into liquid. It happens when molecules of water vapor cool and collect together as liquid water. Water vapor can be found on the outside of cold glasses, the warm side of windows, and in the clouds up in the air.
What is needed by water to evaporate from the Earth’s surface?
heat energy Water easily evaporates at its boiling point (212° F, 100° C) but evaporates much more slowly at its freezing point because of the heat energy required to evaporate the water.
At what height does water vapor condense?
Moist parcels of air may cool more slowly, at a rate of 0.5 ° C per 100 meters/330 feet. Therefore, the vertical ascent of air will reduce its ability to hold water vapor, so that condensation occurs. The height at which dew point is reached and clouds form is called the condensation level.
What happens during condensation?
Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.
Why does water vapor condense in the condenser tube?
The water vapor molecules transfer energy to the colder air. This makes the water vapor molecules move more slowly. Their attractions overcome their motion and they join together or condense to form liquid water.
Why does water flow uphill in a condenser?
To maximize the efficiency of the sample, the water jacket needs to be full of cold water. The water hoses have to be attached in a certain way. The water will fill the condenser if it is forced uphill.
Why does the water flow have to go into the bottom of the condenser and out through the top in the reflux apparatus?
Water should always enter from the bottom of a condenser (the end closest to the flask) and exit from the top of the condenser. Doing it this way always ensures that your condenser will be full of cooling water.
What is the only river that flows backwards?
