Given:
- Student 'A' has water in a bowl.
- Student 'B' has water in a plate.
To find:
The rate of evaporation is faster in which case.
Principle involved:
- The process of conversion of the liquid state of water to the gaseous state is called evaporation.
- The rate of evaporation is dependent on the surface area of the vessel.
Observation:
- Student 'A' is having water in a bowl, whereas student 'B' has on a plate.
- The rate of evaporation is faster in case of student 'B'.
Inference and conclusion:
- When the surface area of bowl and plate is compared, the latter has more whereas the former has less.
- Due to this reason, as the surface area is large in the case of plate, the water with student B evaporates faster.
