Question

AIM
To study the rate of evaporation of different liquids and the different factors affecting it.
In this project you have to do three experiments to study the effects of different conditions on the rate of
evaporation
1) Surface area
2) Air current
3) Temperature
MATERIALS REQUIRED
• shallow plates of same/different radii
• Stopwatch
Experiment 1
Aim: To study the effect of surface area on the rate of evaporation of water.
Procedure: 1)Take 3 plates of different size.
2)Pour 20 ml water in each.
3) Note the time taken for complete evaporation of water in each plate.
