++ FACTORS AFFECTING THE RATE OF EVAPORATION.
1. temperature
>> higher the temperature of the liquid,
faster the rate of evaporation
!! heating a liquid will increase the rate of evaporation
2. humidity of the surrounding air
>> rate of evaporation decreases,
with increasing humidity
!! rate of evaporation increases with lower humidity
3. surface area of the liquid
>> rate of evaporation increases,
when there is more exposed surface area of the liquid
!! larger exposed surface area means more molecules can escape from the liquid
4. movement of air
>> rate os evaporation increases,
when the surrounding air is moving
5. pressure
>> reducing the atmosphere pressure,
increases the rate of evaporation.
6. boiling point of the liquid
>> liquids with lower boiling points will evaporate faster.
