Question: What happens to water droplets?

When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets. Eventually, the drops will become so heavy that they can no longer float in the air.

What do water droplets turn into?

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. The water droplets that form make up clouds.

What happens to water droplets in the air?

Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.

What happens to water droplets when they evaporate?

Once evaporated, a molecule of water vapor spends about ten days in the air. 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 happens when water droplets fall from the sky?

A cloud is composed of tiny water droplets (or ice crystals) that are suspended in the air. If the droplets become large enough,they may be visible as a cloud or fog. They may also fall to Earth in the form of rain (or snow).

Why do water droplets come together?

When air cools, the amount of water vapor it can hold decreases. As air rises, its presssure decreases, thereby allowing it to expand and cool. With sufficient cooling, the air reaches saturation and small cloud droplets begin to form.

Does water evaporate at night?

Evaporation occurs when a liquid molecule of water escapes into the air as a gas. Notice how the rate of evaporation pulses over land: it speeds up during the day and almost disappears at night. Over the ocean, evaporation appears to remain constant, both day and night.

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.

Why clouds are not falling down?

Clouds consist of tiny water droplets (or ice crystals) and, like all objects, they do fall, but at a very slow rate. Cloud droplets remain suspended in the atmosphere because they exist in an environment of gently rising air that overcomes the downward force of gravity.

Can you touch a cloud?

Unfortunately, it does not feel like cotton balls or cotton candy, but most people have technically touched a cloud before. If you wanted to touch an airborne cloud, the best way to do this is either skydiving or in a hot air balloon, though I would not want to be stuck in a cloud while in a hot air balloon.

Does evaporation of water takes place only in sunlight?

So let us write down proof the evaporation of water takes place only in sunlight. This is false evaporation of water may take place in the absence of sunlight. During the daytime all the air surrounding gets heated this bone air provides heat for the evaporation of waters in the absence of sunlight.

Why are water droplets round?

Raindrops start to form in a roughly spherical structure due to the surface tension of water. On smaller raindrops, the surface tension is stronger than in larger drops. The reason is the flow of air around the drop. As the raindrop falls, it loses that rounded shape.

How small are water droplets?

Condensation occurs when the water vapor wraps itself around the tiny particles. Each particle (surrounded by water) becomes a tiny droplet between 0.0001 and 0.005 centimeter in diameter. (The particles range in size, therefore, the droplets range in size.) However, these droplets are too light to fall out of the sky.

Is a collection of water droplets?

Usually a cloud (or fog) forms when the air temperature gets cool enough that the water in the air starts to condense, which means that the water vapor turns into tiny water droplets in the air. The collection of these tiny water droplets make a cloud (or fog) visible to us.

How long does it take for a drop of water to evaporate at room temperature?

Now, I assume that this mass flux remains constant with time since the water is in thermal quasi-equilibrium with the room (a large temperature reservoir), and therefore remains at constant temperature, thus not changing the properties of water. The water takes 1.2 hours to fully evaporate.
