Condensation is the change of water vapor into liquid water and occurs when warm air cools and loses its ability to hold water vapor. There are several forms of condensation, including dew, which forms on cold surfaces at night; frost, which forms tiny ice crystals below freezing; fog or mist, which are tiny droplets suspended in the air in low visibility; and clouds, which form around dust particles in the atmosphere and can be classified by form and height into cirrus, stratus, cumulus, and nimbus clouds.

2. WHAT IS CONDENSATION?
• Condensation is the change of water from its gaseous form [water
vapour]into liquid water.
• Condensation generally occurs in the atmosphere when warm air rises
,cools and loses its capacity to hold water vapour.
• As a result ,excess water vapour condenses to form cloud droplets.
• Condensation is the warming process.

3. CONDENSATION
Condensation takes place
when the water vapour
cools and changes into
water droplets.

4. FORMS OF CONDENSATION

5. 1.DEW

6. DEW
The surface of the earth gets cooled during the night and it
cools the near atmosphere . This causes the water vapour to
condense and the condensed droplets cling on to the cold
surfaces on earth . These water drops are called Dew.

8. FROST
There are places on the earth were the night temperature falls
below zero degree Celsius . Instead of dew ,tiny ice crystals are
formed in such places .This form of condensation is called frost.

9. 3.FOG OR MIST

10. FOG OR MIST
The condensed tiny droplets of water formed by the cooling of air
remains suspended in the atmosphere itself . They can very be described
as clouds close to the earth’s surface . Fog or mist is the result of
condensation around the minute dust particles in the lower atmosphere .
If the range of visibility is less than one kilometre , it is termed fog . The
airports in north India get temporarily closed during winter due to
dense fog .
If the range of the visibility is more than one kilometre , is called mist .

11. 4. CLOUDS

12. CLOUDS
Clouds are formed by the condensation of water vapour around the fine
dust particles in the atmosphere . The water droplets so formed as less
than 0.001 cm in dimension . That is why they remain suspended in the
atmosphere .We can see different types of clouds in the sky . Clouds can
classified according their form and height .Based on form there are
mainly 4 types of clouds.

13. TYPES OF CLOUDS

14. 1.CIRRUS CLOUDS
These are feather-like clouds in the upper
atmosphere in clear weather conditions .

15. 2 . STRATUS CLOUDS
These appear in thick layers in the lower part the sky .

16. 3 . CUMULUS CLOUDS
These clouds resemble huge cotton bundle and are
formed due to strong convection currents . They are large
vertical extent .

17. 4 . NIMBUS CLOUDS
These are dark rain clouds in the lower atmosphere .
These clouds appears dark as it does not allow sunlight to
pass through due to thick concentration of water droplets
.
