Condensation in Water Cycle

Condensation is the process by which water vapor turns into liquid water

Water vapour condenses when it hits a cold surface and forms liquid water.

Let us see a common example of condensation.

If we take a glass filled with ice-cold water, and leave it at room temperature

We will observe the formation of little water dropplets on the glass surface.

This is because the water vapors present in the air get condensed when they come in contact with the cold glass surface.

Let us discuss some examples of condensation seen in our daily life.

When you wear glasses in an A.C. room for long, and then immediately go to a warmer place, the glasses will fog up.

Dew forming on the grass is also an example of condensation.

The mirror becomes foggy during a shower because warm water vapor in the air hits the cool surface of the mirror.

Clouds are also formed by condensation.

Condensation is crucial part of the water cycle because it is responsible for the formation of clouds.

As water vapor rises into the atmosphere, they mix with very tiny particles of dust, soot and salt, which are present in the atmosphere.

When warmer air comes into contact with cooler dust particles the vapor gets deposited on these particles forming clouds.

Condensation is a very important step in bringing water back to Earth.

Let us see how condensation brings back water on Earth.

After a point, the air becomes saturated with too much moisture. The clouds become “too heavy” to carry any more moisture.

So the water comes back to the land in the form of rainfall.

The process by which the water comes back to land via rain is known as precipitation.

Moving on, let us discuss the factors affecting precipitation.

Temperature is inversely related to condensation. When temperature is low, rate of condensation is more.

Cooler air can't keep water molecules separated, so they combine again to form droplets.

Humidity is directly proportional the rate of transpiration. More humidiy means higher rate of cloud formation.

Revision

Condensation is a step in the water cycle.

Condensation is the process by which water vapor cools down to form liquid water.

In our daily life, we see many examples of condensation around us.

Condensation is required for cloud formation in the water cycle.

Condensation is important for bringing water back to land.

Rate of condensation is mainly affected by temperature and humidity
