Question

Answer the following questions in about 150 words.
(ii) What are forms of condensation? Describe the process of dew and frost
formation.

Answer 1

Answer:

Explanation:

The transform of water vapour into water is called condensation. It is caused by loss of heat.

Different forms of condensation are-

1. Dew- The deposition of water vapour in the form of tiny droplets on the colder bodies by condensation is known as dew.

2. Frost- Wen the temperature of air falls below 0 degree C, before the dew point is reached, the water vapour is directly converted into crystal of ice and called frost.

3. Fog- Extremely small water droplets suspending in the atmosphere and reducing the horizontal visibility is fog.

4. Mist- Mist is less dense than fog..

Answer 2

Condensation is defined as it  is a method through which water vapor changes from gaseous to liquid state. When air is cooled below its point of dew, a component of the water vapor can transform to liquid. There is no natural condensation in the room, as it occurs in the enclosed water container.

Step by step explanation

There are 7 forms of condensation

• Dew

The precipitation of water vapor by condensation in the form of small droplets on the colder bodies is known as dew.When the moisture is accumulated on cooler surfaces of solid objects in the form of water droplets   above the surface such as stones, it is  also known as dew . The freezing point is above for formation of dew.

• Frost

When the air temperature drops below 0 degree Celusius  the water vapor is directly converted into ice crystal before the dew point is reached. Frost is nothing but thin layer of ice on a solid surface.

• Fog

Extremely small droplets of water which stay in the atmosphere and reduce horizontal visibility is called as fog.It is formed when  the temperature of an air mass containing a huge amount of water vapor suddenly drops, condensation on tiny particles particles takes place within itself. So the fog is a cloud that has its origin on to the ground. The visibility is low  due to the fog and mist.

• Mist

Mist is less denser  than fog. In mist contains a thicker layer of moisture in each nucleus.  mist  commonly occurs  over mountain regions . Mist is also developed by droplets of water but with less  coalescence. It means the mist is less concentrated and quickly  dissipates.

• Rime

It is created on striking objects like telegraph posts when wet fog has super-cooled droplets instantly freezed. It can often seen on tree tops mountains and in winter seasons.

• smog

The combined effect of droplets from smoke and fog that lower visibility, and this  is called as smog. Smog can also be caused by the burning of large amounts of coal, vehicle emissions and industrial fumes these are nothing but Primary pollutants.

• Haze

Some solid particles like dust, smoke, from fire and insdustry which are not visible to our naked eyes is defined as haze.These dust, smoke and other dry particles obstruct the clearness of the sky.
