(i) The process that intended for study by this experiment is transpiration.

(ii) Transpiration is the process in which water is lost in the form of vapour from the aerial parts of the plant.  

(iii) After the experiment, we observe test tube A is raised up i.e., a loss of weight. In test tube B, the weight remains unchanged.

Reason : In test tube A, loses weight due to the plant transpires and loses water. In B there is no plant so there is no transpiration and the oil on the surface prevents direct evaporation and so weight remains unchanged.  

(iv) As a control experiment.
