Forms of condensation

Forms of Condensation

1. WELCOME CHAPTER 1 – SUN : THE ULTIMATE SOURCE PRESENTED BY SHARAN R Emmanuel college of B.Ed. Training

2. CONDENSATION The conversion of a water vapour into a liquid form is called CONDENSATION CONDTION: Addition of water vapour or fall in temperature, the water vapour in the atmosphere begins to condense.

3. Forms of condensation

4. Atmosphere should reach the saturation level for condensation to begin. Addition of water vapour or due to a considerable fall in temperature. Therefore, water vapour in the atmosphere begins to Condense . Forms of condensation

5. DIFFERENT FORMS OF CONDENSATION

6. 1. Dew Water droplets clinging on to the blades of grass and leaves early in the morning. This is called Dew.

7. 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.

8. 2. Frost The night temperature falls below 0° Celsius in some places on the earth. Instead of dew, tiny ice crystals are formed in such places. This form of condensation is called Frost .

9. FROST

10. 3. Fog or Mist Fog or mist is the result of condensation around the minute dust particles in the lower atmosphere. This may obstruct atmospheric visibility. If the range of visibility is less than one kilometer, it is termed Fog . If the range of visibility is more than one kilometer, it is called Mist .

11. FOG :range of visibility is less than one kilometer

12. MIST : range of visibility is more than one kilometer
