Question

find out minimum five natural phenomenon of evaporation and prove these are natural evaporation?

Answer 1

Evaporation is the process of escaping of  molecules from the surface of liquid at any temperature .
Evaporation is a cooling process.

Some natural phenomenon of evaporation are:

1. Evaporation of water from sea, rivers etc due to sun's heat.
Here the suns heat is absorbed by water molecules and evaporates as vapor.

2. Evaporation of water when clothes are dried  after washing. Due to heat and wind speed ... Water molecules on clothes escape.

3. Water stored in Earthen pots remain cool in summer as the water particles will absorb heat from pot and escapes leaving the water in pot cool.

4.After vigorous exercise we sweat a lot. Due to evaporation sweat is escaped into atmosphere and feel cool.

5. Panting of Dog. Dogs pant to reduce / regulate internal body temperature . Because when they stretch the tongue, saliva present on tongue, gets evaporated by absorbing heat .

By all these examples we can say that Evaporation is a natural phenomenon which does not require any external agent.
