Answer :
Final answer:
Evaporation rate is faster under a fan compared to inside a cupboard. Evaporation slows down on rainy days due to increased humidity.
Explanation:
a) Faster Evaporation: The sample kept under the fan will experience faster evaporation. This is because the moving air from the fan helps to speed up the evaporation process by carrying away water molecules from the surface of the water in the test tube and the china dish.
b) Rainy Day Impact: On a rainy day, the rate of evaporation will slow down for both samples as the air is more humid, leading to less efficient evaporation due to the presence of moisture in the atmosphere.
