PLACE ANSWER HEREExplanation / Answer
Answer 36) Evaporation is the process in which liquid is converted into gas. Factors affecting evaporation is as follow:
1) The flow of wind. More wind faster rate of evaporation. A cloth dry faster in the presence of fan
2) Temperature. Increasing the temperature increases the rate of evaporation, as the molecule will gain kinetic energy as a result of which molecules above average energy would escape fro the liquid.
3) Surface area. Increasing the surface area increases the rate of evaporation.
4) Vapour pressure. Increasing pressure on the surface of liquid hinders evaporation.
5) Intermolecular forces. Stronger intermolecular forces within the liquid molecules decreases the rate of evaporation.
Therefore, the correct ansewer is b) Increasing the surface area decreases the rate of evaporation.
