3. Evaporation :-The process
of a liquid changing into
vapour even below its
boiling point is called
evaporation.

4. Temperature
Surface area
Humidity
Wind speed

5. The rate of evaporation increasing
the temperature of the liquid.
 The rate of evaporation of a
liquid can be increased by heating
it.

7. The rate of evaporation increases
on increasing the surface area on the
liquid.
The rate of evaporation can be
increased by increasing the surface
of the liquid.

9. When the humidity of air is low , then
the rate of evaporation is high, and
water evaporates more readily.
When the humidity of air is high, then
the rate of evaporation is low, and water
evaporates very slowly .

11. The rate of evaporation of a liquid
increases with increasing wind speed.
