उत्तर

The various conditions that favour the process of evaporation are discussed as under :

  1. Concentration of water vapour in air: (humidity level) : If the water vapour concentration is high in air the evaporation process gets slowed down.
  2. Pressure : Evaporation takes place faster when pressure is less and vice versa.
  3. Surface Area: If the surface area is large then evaporation takes place faster.
  4. Temperature : On increasing the temperature, the rate of evaporation increases.
  5. Rate offlow of air : If air is moving over the place all the time, then the concentration of water vapour decreases in the surroundings, thus increasing evaporation rate.
